    An possible reason why the activated carbon used in the exhaust facility of real semiconductor production factory could not be regenerated by scCO2 regeneration was estimated to be attributable to its high boiling point adsorbates which showed a peak in TGA (Thermogravimetric analysis) curve at 400-900°C. This study was conducted to experimentally verify the above insight by using TGA analysis and scCO2 regeneration for the real samples with different loads from the factory. The experimental results showed that high boiling point ratio defined by TGA analysis was less than 4.0% in case of the heating treatment temperature of 200 °C in the exhasut facility of real semiconductor production factory. This result suggested regeneration rate of the activated carbon was higher than 80%. Our scCO2 regeneration process can achieve high efficiency as a practical application.

    Evaluation of CO2 storage capacity in water saturated reservoir rocks is very complex because various trapping mechanisms that act at different rates are involved and, at times, all mechanisms may be operating simultaneously. Thus, in terms of the water saturated reservoir rocks, a reliable estimate of CO2 storage capacity requires a thorough understanding of the mechanisms of CO2 trapping in this system.<BR>The objective of this study is to provide a fundamental knowledge about interactions among CO2, water and rock, and contributes to development of standards for CO2 storage capacity estimation in the water saturated reservoir rocks. In this experiment, CO2 sorption was measured for rock samples (quartzose arenite, greywacke, shale, granite and serpentine) , and mineral samples (quartz and albite) in a CO2 rich dense phase at 50ºC and 100ºC, and pressures up to 20MPa, the condition of which is expected to occur mostly during CO2 injection into pores of the water saturated reservoir rocks. The result obtained from the experiment exhibited a significant sorption capacity of CO2 on all of the samples. At 50ºC and 100ºC, quartzose arenite indicated largest sorption capacity among the other samples in higher pressures (>10 MPa) . Furthermore, comparison with model prediction based on the pore filling model, which assumed that pores of the rocks and minerals will be filled with CO2, suggested the importance of the sorption mechanism in the CO2 geological storage in addition to the pore-filling mechanism.<BR>The present results indicate that the sorption process may have significant and meaningful effect on the assessment of CO2 storage capacity in geological media.

    Sorption isotherms, which describe CO2 storage capacity of rocks, are important for estimating CO2 sequestration potential of geological reservoirs. This study examined CO2 sorption capacity of Kimachi sandstone and Iidate granite in the CO2 rich dense phase, the condition of which is expected to occur mostly in the course of CO2 injection into geological reservoirs because of the displacement of formation water by CO2 pressurization in geological reservoirs as storing CO2 into aquifers, at geological temperature and pressure. CO2 sorption measurements were conducted using both volumetric and gravimetric methods at temperatures of 33∼200°C and pressures up to 20MPa. It was found that Kimachi sandstone and Iidate granite were capable of sorbing CO2 into their internal structures. At 50°C, the amount of CO2 sorption reached the maximum value of 1.4 mmol/g (= 31.4 scc/g) for Kimachi sandstone and 0.7 mmol/g (=15.7 scc/g) for Iidate granite, respectively. Comparison among model predictions (monolayer adsorption, solubility and pore-filling) suggests that the sorption of CO2 onto rock minerals may contribute to a significant portion of the CO2 storage capacity in the course of CO2 injection. <BR>This investigation points out the significance of CO2 sorption onto rock minerals for the possible mechanism in CO2 geological storage.

    The phase equilibrium of the H&lt;sub&gt;2&lt;/sub&gt; + cyclopentane binary clathrate hydrate is important because cyclopentane (CP) has been shown to reduce the equilibrium storage pressures similar to that of tetrahydrofuran (THF). In this work, we apply correlations for the H&lt;sub&gt;2&lt;/sub&gt; + CP binary clathrate hydrate system based on the Gibbs free energy and the Kihara potential. The correlation is also applied to the H2 + THF binary clathrate hydrate system and compared with literature results. It was found that the models could correlate both H&lt;sub&gt;2&lt;/sub&gt; + CP and H&lt;sub&gt;2&lt;/sub&gt; + THF sufficiently. From the calculated hydrogen occupancies and the Langmuir constants of CP and THF, the relationship between hydrate dissociation enthalpy and hydrogen occupancy was studied. The hydrate dissociation enthalpy varied according to phase equilibrium conditions at low pressure. The Langmuir constant of CP was lower than that of THF which implies that the formation of CP clathrate hydrate is more difficult to form than THF clathrate hydrate. As hydrogen occupancies became higher, the hydrate dissociation enthalpies of H&lt;sub&gt;2&lt;/sub&gt; + hydrocarbon binary clathrate hydrate approached a constant value.

    Vapor-liquid equilibria (VLE) and liquid-liquid equilibria (LLE) for water-decane and water-squalane (C_<30>H_<62>) binary mixtures were correlated by Peng-Robinson Equation of State (PR EoS) at temperatures ranging from 573 to 637 K and pressures ranging from 1.3 to 31.2 MPa. The boiling point and critical constants of squalane were estimated from the specific gravity and molecular weight by using Nji method whose applicability to heavy hydrocarbon had been approved by comparing the prediction accuracy for the literature critical constants of paraffins, naphthenes and aromatics. Introduction of two temperature dependent binary parameters into mixing rules was revealed to provide good correlations and it was also suggested that the temperature dependence of volume binary parameter was omissible to reduce the number of parameters in calculations.

    Hydrogen production from glucose in hot-compressed water was experimentally studied at 250〜350℃. It was found that an addition of ZnO as catalyst and H_2O_2 as an oxidant brought about an increase in the yields of CO_2, CO, and H_2. The yields of CO_2 and CO proportionally increased with increasing the amount of H_2O_2, whereas H_2 yield decreased above a certain amount of H_2O_2. The influences of temperature on the gas yields were revealed to be not so significant under the condition in this study. However, it would be noted that the H2 yield was higher at the lower the oxidant addition at all the temperature. Now we are studying on the reaction mechanism and the optimization of the process.

    Microalgae can be regarded as potential biomass resources because of their rapid growth and simple constituents. For utilization the microalgae as biomass, it must be clarified what are controlling the growth rate and the composition of constituent component in microalgae cultivations. In addition, effective utilization may require the cascade processes consisting of separation of valuable components from microalgae and conversion of residuals to useful components. This study was conducted by using Chlorocuccum littorale as a microalga. The experiments were conducted to firstly study the effects of culture conditions (temperature, gas composition and irradiance) on both the cell growth rate and carotenoid productivity and to secondly apply the supercritical CO_2(sc-CO_2) extraction to caroteniods separation from freeze-dried microalgae. The results revealed that the cell growth rate was enhanced by elimination of O_2 from aeration gas and decrease of brightness of light, and that the sc-CO_2 extraction exhibited lower carotenoid selectivity and higher extraction yield with adding ethanol as an entrainer.

    Anthropogenic effects on the climate can be mitigated through various artificial measures. Amongst others CO_2 sequestration on geological reservoirs including deep saline aquifers, depleted oil/gas reservoirs, and coal seams is expected to provide a powerful means for drastically reducing emissions of CO_2 to the atmospheric. It may be an important step to understand the capacity of the host reservoir rock for CO_2 storage in order to assess the potential of CO_2 geological sequestration. In this study, CO_2 sorption capacity of rocks (granite, sandstone and natural quartz) under air dry condition was evaluated experimentally at temperatures of 50 and 100℃, and pressures up to 20MPa using a magnetic suspension balance (MSB), which allows us to measure the rock weight under the presence of supercritical CO_2. The CO_2 sorption isotherms of the rocks obtained showed that the CO_2 sorption capacity increased with the increasing pressure and decreased with the increasing temperature. Especially, the CO_2 sorption isotherms of the natural quartz were nearly the same as that of the granite. The present experimental results obtained from the weight measurements suggest that the sorption of CO_2 onto silica minerals may be the important mechanism for the CO_2 storage in reservoir rocks.

    Hydrogen production from biomass in hot-compressed water was attempted at a lower temperature (300℃). It was found that ZnO was effective for production of H_2 from glucose, however, H_2 yield (=the produced amount of H_2/(the number of 2H molecule in the reactant) was only a few percent. Partial oxidation was attempted to increase the yield of H_2 via CO production because ZnO is an effective catalyst also for water-gas shift reaction. As a result, an addition of H_2O_2 to the reaction of glucose and sugarcane bagasse in hot-compressed water brought about the increase of yields of CO_2, CO, and H_2. The amount of added H_2O_2 affected the yield of all the gaseous products (CO_2, CO, and H_2): CO_2 and CO yields proportionally increased with increasing the amount of H_2O_2, whereas, H_2 yield decreased above a certain amount of H_2O_2. The fact that CO_2 yield was quite high and H_2 yield was still low indicates the increase of controllability of partial oxidation would be demanded.

    The effect of TiO_2 and ZrO_2 on glucose reactions in hot-compressed water was examined by a batch type reactor. Anatase TiO_2 (a-TiO_2) was found to be an acid catalyst that promoted the formation of 5-hydroxymethyl-furaldehyde (HMF), on the other hand, rutile TiO_2 (r-TiO_2) was inactive.. Zirconia (m/c-ZrO_2: monoclic and tetragonal mixture) was a base catalyst to promote the isomerization of glucose. The TPD spectra showed us that the strength of the acidity and basicity is of importance on the glucose reaction

    An on-line technique of sensing CO2 concentration in molten polymers in process extruders was studied with a near infrared (NIR) spectrophotometer. The NIR spectra were acquired at an optical flow cell where the sample solutions were forced to pass through before entering an extruder die. Experiments were carried out for a polypropylene and CO2 system at 473-503K and ∼9.4MPa. The CO2 concentrations were evaluated from the NIR absorbance data after baseline corrections. The plots of the absorption peak area against the apparent CO2 weight fraction determined from the CO2/polymer feed ratio were found to show a linear relationship, suggesting the applicability of the Beer-Lambert's law in terms of weight fraction base. Further experiments at higher CO2 concentrations clearly exhibited saturation behaviors in the plots of NIR absorption peak area against the apparent feed concentration, which meant that below the saturated concentrations the NIR absorption could provide the correct CO2 concentration by using the Beer-Lambert's law and the saturated solubility. Thus it could be noted that NIR spectra can be a useful technique for quantitative analysis of CO2 concentration in molten polymers.

    Dispersion of metal particles into polymer materials by the plasticizing effect of supercritical fluids was investigated. Using supercritical carbon dioxide, a metal precursor of Ag (AgFOD) was infused into polymer materials such as poly (methylmethacrylate) (PMMA), polystyrene (PS) and poly (ethylene terephthalate) (PET). The heat treatment reduced the infused precursor into Ag metal, leading to the formation of a fine particle dispersion layer near the surface of the polymer sample. To investigate the relationship between the infused amount of Ag and sorption of carbon dioxide into these samples, AgFOD was infused in each sample in the temperature range of 35 to 70°C, pressure range of 10 to 30MPa, and infusion time of 0.5 to 4h. It was found that the amount of metal particles infused into polymers via supercritical carbon dioxide had a strong relationship with the sorption of carbon dioxide. Moreover, addition of small amount of acetone as an entrainer to supercritical carbon dioxide could increase the infusion of Ag particles into the inner layer of the samples. It should be noted that metal particle infusion into polymers using supercritical CO2 might be controlled by manipulating temperature, pressure, infusion time, and amount of entrainer.

    In the design and analysis on air washer system with pure water, we need to estimate the vaporliquid equilibrium of related systems. In this study, the vapor-liquid equilibrium for dilute aqueous solutions of volatile weak electrolytes is examined by numerical calculation and experimens. Equilibrium composition in vapor and liquid phase is calculated for NH3-CO2-H2O, SO2-CO2-H2O and NH3-SO2-CO2-H20 systems. Total solute concentration, pH and vapor phase partial pressure of NH3 and SO2 are determined in dilute aqueous solutions from 10-6 to 10-3 mol/kg-H2O in 23°C. Equilibrium composition is predicted and is in good agreement with experimental results in each multicomponent aqueous system. As a result, ionic dissociation and Henry's constants quoted from Edwards' correlation are available even in dilute aqueous solutions of volatile weak electrolytes. These results allow estimate of ionic dissociation and vapor-liquid equilibrium in dilute aqueous solutions of volatile weak electrolytes.

    We propose that the supercritical fluid crystallization (SCFC) method is one of the most promising techniques for preparing organic microcrystals. In the case of titanylphthalocyanine (TiOPc) and diacetylenes, the size and forms of the resulting microcrystals could be controlled by changing SCFC conditions. In particular, the SCFC method for the microcrystallizaton of phthalocyanines is expected to be useful, replacing the previous acid-pasting method.

    More details Close

    Ethyl icosapentaenoic acid (EPA-Et) was concentrated from fish oil with Supercritical CO2 using a rectification column in 9.7 mm internal diameter and 1100 mm effective height. To improve supercritical fluid-liquid contact, "Tawashi" rotor was placed in the extraction cell and the column was packed with Dixon Packing. For greater separation capacity, the column temperature gradient from bottom to top was 35 to 80°C. As the result, reflux flow, waterfall-like in appearance, could be seen, and EPA attained a maximum 90%, although C20 : 4 components were abundantly present in the experimental feedstock. It is thus evident from the present study that EPA can be separated from C20 : 4 components by Supercritical CO2 extraction using rectification column optimized with supercritical CO2-Liquid contact and minimal backmixing.

    Botryococus braunii, BOT-22 can be a producer of hydrocarbon which is secreted naturally from the cell body. It can be useful that some extraction methods can recover with no damage to the living cell, leading to a hydrocarbon production with continuous cultivation. We assessed the "milking" method for a non-destructive hydrocarbon extraction according to literature. In the milking experiments, a heptane extraction solvent was used and rapidly contacted to culture media. Then, a vortex mixer was used for mixing the contents. The extracts recovered by heptane was analysed by GC-FID. The results showed that the mixing and extraction time are very important for the milking and the extracted hydrocarbon was from 3 to 7 wt%-dry cells at each extraction time. After separating the algal cells from the extraction solvent, a fresh culture medium was added to the culture medium and after the 5 days, the cell concentration was recovered. Thus, a method for continuous hydrocarbon production from Botryococus braunii was fairly assessed.

    Understanding phase behaviors of heavy oil mixtures is necessary for designing reaction processes such as upgrading/converting and also efficient separation processes. Since heavy oils are multicomponent mixtures of various heavy hydrocarbons, the phase equilibria are very complicated at higher temperatures and pressures, especially in the case of including supercritical components. Vapor-liquid equilibrium (VLE) generally appears at lower temperature and pressure and with increasing temperature and pressure, liquid-liquid equilibria (LLE) or vapor-liquid-liquid (VLLE) or vapor-vapor (VVE) may appear depending on the conditions of temperature, pressure and composition. This article focused on the phase behaviors of water+heavy hydrocarbon mixtures which the author's group has studied in these years. Based on the classification by van Konynenburg-Scott, typical phase behaviors of water+heavy hydrocarbon binaries were shown to be type III. The phase equilibrium data for water+real heavy oil (bitumen) were measured by using a flow type apparatus which was designed/built for high temperature/pressure measurements of heavy oils system by the author's group. An idea of phase equilibrium prediction methodology for heavy oil mixtures was also presented.

    Cobalt supported on mesoporous silica were prepared via supercritical CO_2 and methanol entrainer at temperatures ranging from 40 to 80 °C, pressures ranging from 16 to 20 MPa and a reaction time of 5 h. The highest yield of cobalt loaded in the silica was 9.9 wt% and the value was obtained by the repeated processing at 60°C, 20 MPa and methanol concentration of 10 mol%. TEM analyses showed highly dispersed cobalt particles in the mesopores. Fischer-Tropsch reactions (230°C, 1.1 MPa) using the obtained catalysts after calcinations was revealed the CO conversion of 46.7 %, which was about 1.5 times higher than the conventional incipient wetness method.

    CO_2 sorption experiments for Berea sandstone, Kimachi sandstone, shale, serpentine, granite, quartz, and albite were conducted using the gravimetric method under air dry conditions at 50℃ and 100℃, and pressures up to 20 MPa. In higher pressures (>10 MPa), Berea sandstone has shown a significantly higher sorption capacity compared to the other samples at both 50℃ and 100℃. It is also shown that the major component minerals for the rocks tested in this study (quartz and albite) have a CO_2 sorption behavior. Comparison of model prediction which assumes that the CO_2 storage capacity of the rock mass is equal to the amount of CO_2 used to fill the pore volume in the rock, suggests that the CO_2 sorption is an additional CO_2 storage mechanism in storing CO_2 process. The present results indicate that the CO_2 sorption characteristics may provide a significant and meaningful effect on the assessment of CO_2 storage potential in geological storage.

    Numerical simulations have been performed to investigate the flow and heat transfer characteristics of near-critical and supercritical CO_2) in the thermally driven high pressure CO_2, circular system proposed by the authors by using of a CFD code, FLUENT. Since the flow can be easily turbulence due to its low kinematic viscosity, the renormalization group (RNG) k-c model was adopted to account for the turbulent flow appropriately. The physical property temperature dependence of CO_2 was considered with piecewise-linear profile (properties vs temperature) under constant pressure. It was found that M-shape radial velocity profile of heating zone was developed by sharply high flow near the wall and relatively slow main flow and that the average circulation flow rate was comparable to that measured by tracer method.

    The phase equilibria are widely utilized for separation processes such as distillation, gas absorption, extraction etc. in chemical industries. These process design and development require the more precise equilibrium data. Recent applications of highly accurate experimental and estimation methods concerned with multi-phase vapor-liquid and liquid-liquid equilibria are introduced in this article.

    We developed a hydrothermal cutter which can prepare any paste from Perilla leaves and stems by tuning the operation condition such as water/sample ratio and temperature. The obtained paste contains the particles whose size is under 1.0 micro meter. This paste was used for prepare the concentrated solution which could be continuously separated/fractionated into flavor compounds and resin ones by using supercritical counter current extraction tower in which the system was rectified by vapor-liquid phase separation induced by tuning temperature/pressure/feed ratio conditions. The simulation method was also proposed based on the Vapor-liquid equilibrium ratio(K-value) information.

    Preparation processes of nano-DDS (drug delivery system) careers using supercritical carbon dioxide (scCO2) method were studied. MCM-41 mesoporous silica and ibuprofen were selected as the model DDS career and model drug, respectively. The experimental results showed that the scCO2 method could achieve a larger amount of deposited drug onto the mesoporous silica material in comparison with the conventional liquid solvent methods. The amount of deposited drug onto MCM-41 depended strongly on the pressure conditions in the scCO2 method, which could be rationalized by the effects of the solubility of ibuprofen and adsorption equilibria of the drug on MCM-41 in scCO2.

The proposed DA - NIAST model could provide accurate predictions of VOCs adsorption equilibria on the various adsorbents in comparison with the conventional methodology by using the ideal adsorbed solution theory (IAST).

    Supercritical fluid extraction-distillation system for separation of high-value products from natural resources was developed. In this system, orange peel powers were extracted by supercritical CO2 with an addition of ethanol and the extract was transferred to thermally controlled distillation tower in which in which extract constituents could be separated into upstream and downstream according to vapor-liquid phase equilibrium for CO2-ethanol systems at specified temperature and pressure. For evaluation of the developed apparatus, two substances (7-hydroxy flavone and anthracene) possessing the similar chemical structures were selected as test samples. The results of distillation showed that the anthracene was highly concentrated in the distillate from the top of the distillation column without accompanying 7-hydroxy flavone at pressure of 12 MPa and temperatures of the tower controlled to be between 353 K at the top and 363 K at the bottom. Nobilethin is one of the highly active natural compounds was also concentrated in the distillate from the top by adding a slight amount of water entrainers. It was demonstrated that the developed system was well-worked towards the highly-selected separation of polymethoxyflavone from Citrus peels.

    本研究では、循環型社会構築に欠かせない将来的な資源作物となりうる「微細藻類」を連続的に生産する新規高圧バイオマス・プロセス構築の基礎を築くとともに、高圧環境での微細藻類生育挙動の検討を通して生物工学に対して新たな学術的知見を与えることを目標とした。平成19年度は、前年度と同様に高いCO_2固定能を有し高密度培養を可能とする緑藻Chlorococcum littorale(以下C. littorale)からのエネルギー成分(糖質・脂質)の生産に着目して、その生産性の観点からC. littoraleの資源作物としての可能性を検討した。プロセスの構築における代謝物生産の制御に関して、本研究ではガス成分ならびに前年度の知見である培地N源濃度の依存性を実験的に検討した。 O_2とCO_2の分圧を制御するとともに、増殖に与えるイオンクロマトグラフィーを用いた培地成分の定量分析を行った。その結果、増殖に与える培地中N源(硝酸イオン)の影響は極めく、細胞濃度と硝酸イオンには負の線形関係が成立することが示された。すなわちN源の欠乏とともに増殖が停止、さらには細胞が肥大化する傾向となり、O_2濃度の増加に伴い特に澱粉質の糖質割合が増加することを実証した。さらに、C. littoraleの脂肪酸生産に与えるガス成分の影響を検討した結果、O_2は増殖の抑制因子とともに脂質生産の観点からは抑制因子であることが明らかになった。 以上より、従来光呼吸速度の増加により増殖速度の低下を誘因する溶存O_2が、N源欠乏下では糖質(澱粉)生産または脂質(トリグリセリド)生産の重要な制御因子となることが実証された。得られた成果を現在投稿論文としてまとめている。

    This is the final report for the project, Development of a high-temperature, high-pressure, continuous microplant for super high speed reactions. In this project, our goal was to develop a conceptual microplant reactor system that could be used to bypass many of the current technological limitations of using high-temperature, high-pressure water such as safety, plugging with solids, and corrosion. To do this, we used the concept of a batch microreactor, that would be used in a continuous manner like that of a printing press. In this way, the use of hydrostatic pressing would allow safe application of pressure, and ideally, chemical heating by mixing two or more substances together, would allow achievement of supercritical conditions and thus high-speed reactions. By performing high-temperature, high-pressure reactions in this manner, it is possible to solve known technological problems. First, reaction of cellulose mixtures were studied. Then, a gel was evaluated for transporting the cellulose mixtures including its reactivity.. Next, chemical heating was studied with thermal methods including thermographic imaging. Finally, reactivity of high concentration mixtures was studied. In this project, we could make progress toward the topic and made the following accomplishments: (i) patent for describing the apparatus (Japanese, English), (ii) study of cellulose hydrolysis reaction at high-pressures (> 600 MPa) in a batch microreactor, (iii) evaluation of a gel suitable for transporting the cellulose into the microreactor and its reaction characteristics, (iv) experiments and evaluation of a method for chemically heating the mixture in a microreactor to reaction condition, and (v) various presentations on aspects of the project. Aspects of the work that will require future study include: use of catalysts, choice of substrate for transporting materials, separation methods for product materials, and throughput and process control. In conclusion, the system designed is practical and can be used to process materials at high-temperatures and high-pressures with great safety and with highly-reliable operation.

    出土木材は,水浸中に組織中のセルコールが加水分解されるため,非常に脆い構造になっており,保存のためには補強と乾燥の両者が必須である。現法(主流)は,出土試料をPEG水溶液に浸漬させ,順次高濃度化させることで,木組織内の水をPEG水溶液と置換させ(含浸過程)、その後に自然乾燥あるいは真空凍結乾燥を行って水分を除去するものである.本研究は,この乾燥に対して超臨界流体を適用すれば界面応力を抑制でき結果的に収縮なしの乾燥が可能であること,ならびに高拡散性の超臨界流体を利用することによる含浸過程での時間短縮を期待したものである。 昨年度は,通常のPEG/糖アルコール含浸法で処理した木製品の脱溶媒へ超臨界CO2を適用した場合について実験を行い,寸法変化は測定5ヶ所においていずれも収縮が0.5%以下の良好な結果を得た。しかし,電子顕微鏡で観察したところ、マンニトールは木組織まで完全には入っていない。その原因としては,含浸時間が十分ではない状態でエタノールと親和性の高いCO2の導入により表面付近でマンニトールが析出したためと考えられた。 本年度は,エタノールにもある程度の親和性のあるPEGを主対象として,気液飽和状態(低圧)のCO2含浸+乾燥実験を実施した。まずPEG水溶液を作成し,それに木材を含浸させ,次にエタノール溶液浸漬させ,溶媒置換を行う。ついで超臨界抽出により完全な乾燥を行う手順を採用した。 PEG4000を用いた実験では,試料濃度,含浸時間,含浸温度,圧力を変化させたところ,いずれも木組織表面部分へのPEG4000分子の進入は確認されたが,内部までは拡散していない状態であった。そこで,この原因が,PEG4000分子の拡散性とエタノールへの低い溶解度にあると推察し,より低分子量のPEG400およびPEG500を共溶媒としての効果を期待して併用したところ,条件によっては木組織の内部まで完全ではないが,一部PEG分子が確認され,PEG混合の有効性が示唆された。

    Dimethyl carbonate (DMC) is a high-value added material because its application is quite wide such as an intermediate of polymer, fuel additive, and so on. A green synthesis of DMC is direct production from CO_2 and methanol. For the reaction, a catalyst is required to proceed effectively and ZrO_2 catalysts have been found to be suitable. The byproduct of the reaction is water and the water makes the DMC yield lower because of chemical equilibrium. In order to enhance the DMC yield, removal of water from the reaction, system is strongly demanded. In this study, we planed to develop a new synthesis process of DMC from CO_2 and methanol by a thermal driven loop reactor. The thermal driven loop reactor has a heating part for the reaction and a cooling pert for the elimination of water. The employed catalyst and the dehydration agent were ZrO_2 and molecular sieve 3 A, respectively. The optimization of the reaction condition was explored through the investigation of phase equilibria and the reaction behavior. Especially, the effect of the amount of the dehydration agent was evaluated. Based on the experimental studies, the model development was performed and resulted in clarification of a controlling factor of the process. First of all, we evaluated the capability of dehydration agent in high pressure reaction media for methanol-water system. As a result, the dehydration agent worked well in the thermal driven loop reactor (temperature of the heating pert : 150-160 ℃, temperature of the cooling pert : 60 ℃). Next, the phase equilibria of CO_2-methanol-water-DMC system was calculated to explore the single phase region, by a model that was created from the basis of the literature. At the decided reaction condition from the calculation (the reactor : 170℃, the dehydration pert : 25℃, pressure : 15MPa), we performed the DMC synthesis by the thermal driven loop reactor. The DMC yield was finally attained 15 mol% (on the basis of the loaded amount of methanol), whereas the DMC yield in a batch reactor at the same reaction condition was merely 1 mol%. We developed a kinetic model for the DMC synthesis by the thermal driven loop reactor to know the controlling factor of the process. Then the model tells us that the flow rate of the reaction fluid in the loop reactor was controlling factor and that the modification of the dehydration pert must be needed to improve the performance of the loop reactor.

    A closed-loop high-pressure circulation system for supercritical fluids for analytical analyses was developed. The system operates on the principle of density differences induced by heating and cooling two different parts of the flow loop. The system was tested with textile materials. A method to measure the velocities was developed that used an organic solvent tracer. Performance of the system was evaluated by measuring average flow velocities attainable with CO_2. Initially, average flow velocities as high as 4 m/min could be obtained with heating and cooling temperature differences of 3 to 8℃. One-dimensional finite-difference simulation could predict the velocities to within 35%. Empirical equations could correlate the velocities to within 10%. Computational fluid dynamics (CFD) simulations were made. The CFD simulations could describe the flow velocities well from the experimentally measured temperature profiles. A new design for the heater is suggested based on CFD analysis that uses baffles and improves heater performance. System performance was improved to achieve flow velocities as high as 7 m/min through the use of internal heating and consideration of the pseudocritical point.

    出土遺物に対して文化財科学(保存科学)は「出土から展示・収蔵」までの全般において関わり、遺物が内包する情報を最大限に残存させ、また施した処理法・技術も合わせて後世に伝える使命を持っている。処理技術は常に現行法より良好な方法を模索しており、多くの研究者が取り組んでいるところである。出土水浸木製品に対する保存処理は、PEG、糖アルコール、高級アルコールなどの強化剤含浸法や真空凍結乾燥や加熱乾燥などの乾燥方法が一般的であるが、その工程上、気相-液相もしくは固相-気相の2相を通過する際の界面応力が起因して引き起こされる変形・収縮を避けられないのが実情である。 本研究では、二酸化炭素を超臨界状態下で出土水浸木製品に適用したが、その内包されている溶媒が超臨界二酸化炭素と相溶解することにより2相をまたぐことなく、均一相下で処理が可能であることから、変形・収縮を軽減できる乾燥方法として有効であることをまず確認した。 次に、二酸化炭素の高い「拡散性」「溶解力」から、処理の難しい脆弱な有機質遺物への処理に対して有効であることが実験的に示唆されたため、それらの結果を基に出土漆製品への処理に適用を試みた。その結果、変形・収縮が0.5%以下の良好な結果を得た。また、超臨界状態の二酸化炭素の持つ「ミクロ構造まで入りこむ」特性から、従来法では難しかった漆膜の微小穴から木胎組織の細部まで強化薬剤の含浸が確認された。さらに、その処理期間は従来の強化剤含浸方法に比べて大きく短縮することが可能であった。超臨界二酸化炭素を用いた出土木製品の乾燥メカニズムについては、超臨界流体GC用FID検出器を応用した実験から、出土木製品内溶媒の乾燥工程を把握し、その結果から乾燥モデルを構築するに到った。

    Polyphenyleneoxide (PPO) is one of the important engineering plastics showing excellent mechanical, thermal, electrical and chemical properties at higher temperatures. In industry, PPO has been produced by oxidative-coupling reaction in toluene solvent and it has been pointed put that the solvent recovery plays an important role in determining the process feasibility. Additionally the viewpoint of green sustainable chemistry has brought the trend of solvent-free synthesis even for polymer industry. From these backgrounds, the synthesis of poly (phenylene oxide) (PPO) has been carried out in supercritical carbon dioxide (scCO_2) at 40 ℃ and 15 Mpa (one-step polymerization). The maximum yield and the weight-average molecular weight (Mw) of the synthesized PPO were ca. 70 % and 10,000 respectively. Two-step polymerization at 55 ℃, 22 Mpa or 70 ℃, 30 Mpa for 8 h was also tried successively after the synthesis at 40 ℃, 15 Mpa for 20 h, leading to increase the maximum yield and the Mw of the PPO up to ca. 80 % and 20,000 respectively. A small amount of diphenoquinone (DPQ) was produced as a by-product of PPO synthesis and its yield for the two-step polymerization was slightly larger (1.7 %) than that (ca.1.2 %) for one-step polymerization at 40 ℃ and 15 Mpa. The synthesized PPO was found to have similar glass transition temperature (T_g) of 200 ℃ to commercial one. These results indicated that the roles of ScCO_2 in this polymer synthesis were not only reaction solvent but also plasticizer for the polytmer, which allowed for us to progress the polymerization even after polymer-scCO_2 phase separation.

    The objective of this research was to develop a simple technique for measuring pressure for a hydrothermal diamond anvil cell (HDAC) and to use the technique with a HDAC to visually study formation of oxides in supercritical water. Hydrothermal reaction of Al(NO_3)_3 in water was investigated at temperatures up to 421 ℃ and pressures up to 850 MPa with the diamond anvil cell system. A number of gelatinous phase transitions were observed that seemed to play a key role in boehmite (AlOOH) formation. At high Al(NO_3)_3 concentrations (0.32 M) and high densities (1060 kg/m^3), high pressure induced formation of a gel-like phase and the phase formed seemed to be much less reactive than solutions at lower densities (400 to 670 kg/m^3). At densities closer to the critical density of water, as heating occurred, the gelatinous material precipitated and redissolved into solution prior to intense precipitation around the apparent critical point. A model for the aluminum hydroxocomplexes in solution was developed that showed that cationic species were the main species present at high density conditions. Nitrate ion seemed to play a key role in the gel-like phase formation and boehmite particle production. We followed up on this with additional batch experiments and found that for the supercritical case, that nitrate does not form in the crystallized boehmite phase. We found that boehmite nanocrystals can be prepared without nitrate impurities under supercritical hydrothermal conditions in contrast with the other results, which suggested that hydrothermally produced boehmites produced from nitrate starting materials were contaminated with difficult to remove nitrates.

    When a liquid phase in a material is changed to supercritical state or exchanged to a supercritical fluid, it is possible to dry the material without phase change, consequently without the dimensional change. This drying method is called supercritical fluid drying. In this study, we have developed a new conservation technique for wet organic archaeological materials with supercritical carbon dioxide. Since it is difficult to dry wood by extracting water with supercritical carbon dioxide, it is necessary to use ethanol that is soluble to both water and carbon dioxide. The two methods were investigated. In one of them, firstly water in a material was exchanged to ethanol, and then supercritical fluid drying was carried out. In another, both impregnation and drying processes were conducted simultaneously. In former method, it was considered that elevation of elevation control of temperature during drying process effects on wood sample shrinkage. In latter, it was suggested that wet organic archaeological materials were treated successively owing to rapid impregnation of reinforcement chemicals and drying without phase change. It is significant that supercritical fluid drying was proposed as a new conservation technique for wet organic archaeological materials in this study. A further direction of this study will be to develop appropriate conditions of treatment according to the materials and the degradation degree of the wet organic archaeological objects.

    We have developed the new heavy oil upgrading system in supercritical water. In supercritical water, partial oxidation provides effective CO formation, which leads to water gas shift reaction. The hydrogenation of heavy compounds and hydrodesufurization can be expected in partial oxidation without expensive hydrogen or catalyst. We chose the asphalt as a heavy oil model compounds. Supercritical water and supercritical water partial oxidation treatments were applied to the reforming of asphalt. Asphalt was converted at 613 - 673 K, 0 - 0.5 g/cm^3 of water density under argon or air atmosphere. The increase of temperature enhanced the conversion of heavy oils. Under an argon atmosphere and 0.5 g/cm^3 of water density, the asphaltene conversion increased and the sulfur reduction increased with increasing temperature. At 673 K, the asphaltene conversion increased and the yield of CO_2 increased with an increasing water density. Water apparently participated in the reaction and its hydrogen was used for the formation of maltenes. Under an air atmosphere at 673 K, asphaltene conversion was lower but the sulfur reduction was higher than those obtained in argon atmosphere. Experimental results indicate that sulfur moved into the coke. As a result, supercritical water can be an effective solvent for heavy oil conversion. Supercritical water partial oxidation can provide the reaction atmosphere for desulfurization of heavy oils.

    We have developed a new vibrating tube densimeter that is capable of measurements of up to 870 K and pressures to 70 Mpa. The densimeter features a δ-shaped design to enhance the length of vibration harmonics, laser-doppler detection of of vibration, wide-range piezoelectric input stimulus, real-time display of all vibration modes, and the elimination of all magnets and tube attachments. Vibrational stimulus is applied to a tube filled with the substance of interest over a time step with a piezoelectric actuator. The input stimulus is simultaneously sensed by computer. A helium-neon laser vibrometer is used to detect transient vibrational changes and an FFT analyzer provides all vibration modes. In the calibrations, the 5ィイD1thィエD1 vibrational mode was used to achieve the greatest sensitivity. A statistical method was applied to develop a calibration equation that was valid over a wide range of temperatures and pressures. A flow apparatus was constructed to PVT at high-temperature and high-pressure conditions. The system consisted of a syringe pump feed, high temperature oven with preheat, densimeter and syringe pump receiver. The feed pump was run in constant flow mode while the receiver pump was run in constant pressure mode. With this apparatus, densities of water, methanol, or water+methanol mixtures were measured at supercritical conditions with an accuracy of 0.006g/cmィイD13ィエD1, which is fairly larger number than the resolution. The new densimeter along with the laser detection method eliminates magnets and extends the range of current vibration-type densimeters.

    Supercritical carbon dioxide (scCOィイD22ィエD2) extraction of alkali metal ions from aqueous solutions (K+, Na+ : 1.7 x 10ィイD1-4ィエD1 mol dmィイD1-3ィエD1) with ligands was investigated. Conditions of the experiments were 40℃ with pressure ranging from 10 Mpa to 18 Mpa. Ligands used were crown ethers (18-crown-6, cis-dicyclohexyl-18-crown-6 and 15-crown-5) and glymes (triglyme and tetraglyme). Extraction of KィイD1+ィエD1 or NaィイD1+ィエD1 with ligand in scCOィイD22ィエD2 gave negligibly low recoveries that did not vary with pressure. However, in the presence of an additive, pentadecafluoro-n-octanoic acid (HPFOA), the recoveries increased clearly for both sodium and potassium ion extractions. This is because the HPFOA ionized and apparently supplied its anion which has COィイD22ィエD2-philic fluoro-alkyl chains. Based on the experimental results, a chemical equilibrium model was developed to analyze the extraction mechanism. For crown ether systems, the recoveries showed simple behavior, and the extracted complexes (alkali metal ion : ligand : counter ion) were confirmed to be monomeric (1:1:1). For glymes systems, the recoveries showed various behavior and tended to decrease at high ligand concentrations. This seemed to indicate consecutive complex formation in the aqueous phase. The results of this study show that alkali metals can be extracted with scCOィイD22ィエD2 using ligands and recovery of the metals can be greatly increased by adding a substance that can supply a COィイD22ィエD2-philic counter Ion. Rerading the reverse micell formation, an apparatus for in-situ dynamic laser scattering measurement was developed. With this apparatus, it was found that perfluoro-polyether can be a good surfactant for reverse micell in carbon dioxide in the presence of warer, however direct evidence of the micell could not be obtained because of lackness in agitation power of the experimental setup.

    We have developed a hydrogenation process of waste plastics through partial oxidation and water gas shift reaction in supercritical water. In this research, for the development of the process, we conducted the basic study of the key reactions, namely 1) pyrolysis of hydrocarbon, 2) partial oxidation of hydrocarbon, and 3) hydrogenation through partial oxidation and water gas shift (WGS) reaction in supercritical water. The results are as follows. 1) Measurement of phase equilibria of hydrocarbon - supercritical water system We have developed the new equipment (vibrational density measurement apparatus for high temperature and pressure) to measure the phase equilibria of hydrocarbon - supercritical water system. 2) Pyrolysis of hydrocarbon in supercritical water Polyethylene pyrolysis experiments were conducted by using batch reactors. The results showed that l-alkane/alkene ratio increased and product distribution shifted toward shorter chain hydrocarbons with increasing water density. This result can be explained by considering change of the reaction phase with water density. 3) Study on hydrogenation of hydrocarbons through partial oxidation in supercritical water. The experiments of partial oxidation of n-hexadecane in supercritical water were conducted by batch reactors. In the results, the selectivities of CO and n-alkane formation were enhanced with increasing water density. The increase in n-alkane selectivity indicates that the produced CO reacted with water to produce H2 followed by the hydrogenation of l-alkane to n-alkane. We also conducted the experiments of partial oxidation of CH4 in supercritical water using a flow apparatus. The selectivity of CO increased with increasing water density. We applied a radical network model, which is commonly used for the gas-phase oxidation of CH4, for describing the partial oxidation of CH4 in supercritical water. Modifying the elementary reactions of forming H2O2 with considering the water density effect, we could described the reaction rate and the product distribution of the partial oxidation of CH4 in supercritical water by model. 4) Designs of a continuous process We made a feasibility study for a continuous process of partial oxidation of hydrocarbon based on the above experimental results. The results suggest that a) the feed concentration of hydrocarbon should be higher than 10%, b) oxygen concentration should be around 15%, and c) liquid phase feeding of oxygen is preferable. The above results suggest that catalytic hydrogenation through partial oxidation and water gas shift reaction in supercritical water have a high potential for hydrogenation of hydrocarbons.

    We have developed a hydrogenation process of heavy oil through partial oxidation in supercritical water. For the development of the process, partial oxidation of hydrocarbon and water-gas shift (WGS) reaction in supercritical water are key reactions. In this research, we conducted the basic study of these reactions. The results are as follows. 1) Study on partial oxidation of hydrocarbon in supercritical water Partial oxidation of n-hexadecane (n-C_<16>) in supercritical water was conducted using batch reactors at 400゚C and the effect of water density on the partial oxidation of n-C16 was investigated, In the result, the selectivity of CO formation increased with increasing water density. Partial oxidation of methanol and methane in supercritical water was also conducted using a flow apparatus at 380゚C - 400゚C of reaction temperatures and 10 MPa - 25 MPa of reaction pressures. At lower conversion and higher water density, the selectivity of CO formation increased. 2) Measurement of reaction rate of water-gas shift (WGS) reaction in supercritical water The reaction rate of WGS reaction in supercritical water was measured using a flow apparatus at 380゚C - 400゚C of reaction temperatures and 10 MPa - 30 MPa of reaction pressures. The rate of WGS reaction was changed specifically at the critical point of water and increased slightly with increasing water density. 3) Study on catalytic hydrogenation of hydrocarbons through WGS reaction in supercritical water Catalytic hydrogenation of hydrocarbons (naphthalene, carbazole, heavy oil, and so on) through WGS reaction in supercritical water was investigated using batch reactors. The rate of catalytic hydrogenation of hydrocarbons under SCW+CO atmosphere was higher than that under SCW+H_2 atmosphere. Furthermore, the rate of catalytic hydrogenation of hydrocarbons under SCW + CO_2 +H_2 atmosphere was higher than that under SCW+h_2 atmosphere. These results suggest that WGS reaction provides an active species for a catalytic hydrogenation of hydrocarbon in supercritical water. The above results indicate that catalytic hydrogenation through partial oxidation and water-gas shift reaction in supercritical water is an effective method for hydrogenation of hydrocarbons.

    The objective of this research was to develop a repid and continuous production process for phosphor (YAG : Tb) fine particles by supercritical water crystallization method. The relationship between properties (crystal sturacture, particle size and particle size distribution) of particles produced and reaction conditions (reaction temperature, pressure, reaction time, composition of solution and alkali mole ration of solution) was investigated experimentally. Al (NO_3) _3, Y (NO_3) _3 and TbCl_3 mixed aqueous solution was used as the starting materials. Potassium aqueous solution was used to vary the alkali mole retio of solution. Experiments were performed with a newly-deveolped flow type apparatus. From these results, the alkali mole ratio was important factor for production of single phase YAG particles. Reaction temperature and pressure affected crystalline size and lattice constant of particles. High temperature and low pressure leaded to produce particles with high crystallinity. Emission properties of particles produced was studied by comparison with particles produced by a conventional solid state reaction method. Properties of particles produced by the method in this work were comparable with the conventional method. Continuous (1.5g/h) and rapid (<1 sec.) production of phosphor (YAG : Tb) fine particles was found to be practical with the supercritical water crystallization method.

    This work was conduted as a fundamutl study of applying supercritical fluid to synthetic rubber production processes. The researchtopicsare followings ; 1) removal of solventand unreactedmonomer from polymer solution with supercriticalfluid , 2) solution polymerizationin supercriticalfluid. The supercriticalfluid usedin this work is supercritical CO2 sinceit allows for us to operate around room temperature due to its critical temperatureof 31C and to removeitself easily via decreasingpressure. Desolvation experimentwas performedwith a supercriticalextraction apparatus. Polybutadiene was used as a polymer sample and n-hexane as a solvent. The extractionat 40C and 150 Mpa revealed that supercritical CO2 can removefairly amount of n-hexane and reduce the concentration of n-hexanein polymersolution upto 1wt % at S/F of 100. Partition equilibrium coefficient between supercritical CO2 and polymer has been measured at infinitely dilute state via chromatography technique with a new experimental apparatus. The equilibirum coefficient was indispensableto evaluate the remaing solvent in polymer products. Experiments were carried out with three packed columnspreparedin this study in the pressure range of 8-20Mpa and at temperatures of 80-140C.The obtained data showed that the weight baed partition coefficientsare in the range of 1-2 and increased with temperature and pressure. An equation of state which can be applied to both CO2 anf polymer, was used for correlation the data, and its equation paraneters were determined with the experimentaldata. With the optimized parameterswe can predictthe partition equilibria in the wide range of solvent concentration in polymer solution and design the desol vation process in polymer Production with supercritical CO2. As a firstattempt, radical polymerization of stirenein supercritical CO2 was conducted with AIBN as an initiator at 70C and 0.1,8,15 and 20 Mpa by varying the 4 reaction time. The monomer conversion was determinedby weighing the produced polymer. The conversiondata suggested that the polymerizationat 0.1,8Mpa is quite similar to bulk polymerization of stireneand that in organic solvent while the reaction ratesat 15 and 20 Mpa are slow, which may be attributableto CO2 playing a role as a dilutantin the reactionsolution. Accordingto the molecularweight, the polymer pricipitation took place in the course of polymerzation because of small solubility of high molecaular weightpolymer into CO2. This discussion was partly supportedby the simulation results with the literaturedata for rate constantspropsed for or ganic solvents. It should be noted that the phase behavior of reaction systemis key to elucidate the mechanism of polymerization in supercritical fluids.

    The objective of our work was to examine supercritical water as a reaction solvent. We made both molecular simulations and experimental measurements in our studies. For the simulations, we used SPC model that was modified to have flexibility and to have cHarge located at the center of mass. We grafted a new intramolecular potential function to give the model applicability at high temperature. The new model could provide superior predictions of IR-spectra, pressure-volume-temperature, relations, saturation conditions, self diffusion coefficients, and other properties compared with current literature models for water. We also examined the dielectric behavior experimentally and theoretically. For the experiments, a new cell was constructed and used to study the behavior of hydrogen bonds as temperature and concentration of the system was varied up to about 373K.Alcohols were used as the solutes. We found that there were several regions of hydrogen bonding but that there was a continuous change in the time constants, in contrary to that reported in the literature. The three regions disappeared as the temperature was elevated indicating a weakening of the hydrogen bonding. However, simulation shows that hydrogen bonding still exists since bifurcated structure was found.

    超臨界水中を利用した反応プロセスが最近活発に検討されているが,その明確な反応機構は未だ解明されていない。反応中間体の水和 構造とその動力学 が反応機構の解明のブレークスルーと考えられるが、この点に関する検討は皆無であり、本研究ではこれを研究目的とした。 実験的検討が現時点では困難なことから計算機シミュレーションを用い、超臨界水中での反応物質ならびに中間体への溶媒分子のクラスタリングについて検討した。 まず,水に対して現在までに報告されているポテンシャルモデルを検討した。その結果,超臨界水にはRigidモデルよりは分子内自由度が考慮されているFlexibleモデルが適当と判断し,その中で関数形の簡単なTaukan-Ramanモデルのパラメータを赤外スペクトルや密度データを用いて最適化した。次に,分子間ポテンシャルパラメータの最適化を行い,本モデルでの臨界点の推定を行った。得られたポテンシャルモデルを用いて,NaCl水溶液を対象として,室温から臨界点近傍までの広範囲で,分子動力学シミュレーションを行った。P-V-Tデータからは、電解質の添加により体積が減少すること,すなわちイオン周囲に強い水和構造が形成されており,この傾向は臨界点近傍ほど顕著であることが示唆された。また動径分布関数からは温度上昇とともにイオン周囲の水分子の分布頻度が低下するが,これはNa_+よりはCl_-のほうが顕著であった。さらに,水和分子の安定性について相対運動エネルギーに立脚した溶媒和分子の識別定義を提案し,これに基づいてイオン周囲の水和の安定性を調べたところ,Na_+については水和分子の絶対数は常温に比較すると超臨界状態ではかなり少ないが安定性については,ほとんど同じであるという結果が得られた。

    金属アルコキシド重合は単分散性の良い無機微粒子の製造法として注目され、これを応用して液晶ディスプレーのスペーサーやコーティング剤などに活用されている。この方法により粒径分布の狭い粒子を工業的に製造するためには、シ-ド重合法(あらかじめ生成した反応系を希釈してモノマーを添加する多段重合法)が適用されているが、その操作条件の選定や装置設計には試行錯誤的な方法に頼らざるを得ない状況にある。これは、従来の研究がシ-ド重合を対象としたものがほとんどないこと、さらに従来の研究の主眼が平均粒径と反応条件の関係に置かれ、粒径分布そのものを対象としたものが少ないためであると思われる。したがって、この制御法を確立することは極めて重要な工業的課題である。 そこで本申請者らはこのような問題を解決するために、反応条件を種々に変えた場合の粒径分布ならびに生成粒子の多分散性の指標となる変動係数の経時変化の測定を行うことにより、単分散性粒子を生成する最適なモノマー濃度が存在することを明らかにした。また、単分散性粒子が生成する条件下では、反応初期において非球状の微小粒子が凝集して大きな粒子が生成し、その大粒子が粒径分布を維持したまま微小粒子を吸収しながら成長する2つの過程を経ることがわかった。これらの実験結果から、粒子生成過程と粒子成長過程の2つを同時に考慮したモデルを導出し、粒径分布ならびに変動係数の経時変化についての計算を試みた。その結果、モノマー濃度に対する平均粒径や単分散性について本実験結果と同様な傾向を示すことができた。また、本研究によて、従来、分散安定性に関して主要な因子であるとされていた静電反発力よりも水和斥力の方が生成粒子の粒径分布に大きく影響することがわかった。

    The objective of this study is the development of method for molecular designing hydrogels to switching-functional materials. To this end, the experiments and theoretical researches have been done on swelling equilibria of nonionic hydrogels and polyelectolyte hydrogels. Through swelling experiments on N-substituted acrylamide gels which show thermoshrunken type phase transition, it was found that hydrophobic interaction plays an important role in the transition and the phase behavior can be varied by changing the N-substitute and crosslinking density, and by adding electrolyte into the network chains of gels. On the phase behaviors of polyelectrolyte gels, electrostatic interaction between electrolyte in the gels and counterions should be taken into account. Regarding prediction of the phase transition, we pointed out the limit of applicability of Flory-Huggins theory and the necessity to consider the orientation interaction such as hydrogen bonding and hydrophobic interaction for nonionic gels.

    高分子の性質はその単量体の性質でほぼ決定され、さらにゲルはゲル網目を構成している高分子の性質に依存するとされている。本研究では,現在までにゲル相転移が確認されているが水溶液中であることに着目し、水分子の相互作用という観点から低分子から高分子・ヒドロゲル系の相平衡推算モデルを開発することを目的として、まず水分子の相互作用を反映できる状態方程式について、低分子および高分子系それぞれについて検討した。 低分子系については、Jorgensenらのグループ寄与状態式(以下GC-EOS)の適用性について検討した。GC-EOSは、分子の大きさを考慮した自由体積項およびグループ間の相互作用に基づく引力項より成る。さらに、グループの連結性を考慮するために、新たに有効表面積の概念を導入した。推算を行ったところ、従来から推算が困難とされているCO_2-水-エタノール系を含めて3成分系の推算精度は良好であった。CO_2-エタノーループルパノール-水4成分系については気液共存組成の推算誤差はやや大きいもののタイラインの傾きに関しては良好で実験値の傾向を表わすことができた。 次に高分子系については、Prangeの格子モデルについて検討した。ゲルの膨潤圧データからパラメータを決定し、膨潤平衡推算を試みた。膨潤域での推算精度は十分とは言えないが、架橋度による転移幅の違いを弾性項のみで表現することができた。転移温度の推算値は実験値と異なったが、これは本式の高分子溶液の液液平衡に対する適用性がゲルの転移点の推算結果にも現れたものと考えられる。これらのことから本式は弾性項よりは混合項に検討すべき点があると結論できる。

    高分子のゾル・ゲル転移機構についてはその重要性から古くから研究が行われてきたが、溶液中での高分子の存在形態は複雑で、長い間十分な解析が行われずにいた。ところが最近になってこのゾル・ゲル転移現象を一種の臨界現象と見なす考え方が提案され、再び勢力的な研究が行われ始めている。ゾル・ゲル転移を臨界現象と見なせるとすれば、物性の変化にはスケーリング則が適用し得る筈であり、ゲル化の過程が統一的な規則で表せる可能性がある。従来このスケーリング則の適用性は非電解質の高分子を中心に適用性が検討されてきたが、電解質高分子についてその適用性を検討するのが本研究の目的である。本研究としては、電解質高分子として多価イオンの添加により高いゲル化能を示す電解質多糖を用いた。またこの高分子に比して屈曲性に富んだ分子構造の高分子電解質についても実験を行う予定である。高分子多糖を用いて実験では、ゾル・ゲル転移に伴う粘性率と弾性率の測定を行い、電解質添加による反応率と高分子濃度の関係を調べた。その結果反応率一定で高分子濃度を変えた場合ならびに高分子濃度一定で反応率を変えた場合において、粘性率指数は0.8〜1.2であり、一方弾性率指数は1.6〜2.0の値を取り、それぞれの場合に同一の値を取ることがわかった。またこれらの値は中性高分子についての既往の値と類似の値を取ることがわかった。ところが、臨界反応率の濃度依存性を調べたところ、その指数の大きさは中性高分子の値に比して約半分程度と小さい値を示すことがわかった。この電解質多糖の特徴については、高分子の剛直性を考慮したモデルを提案し、説明することに成功した。また本モデルにより、電解質多糖の高いゲル化能が分子内架橋を形成しない、効率的な分子間架橋を形成することに基づくことを示唆することができた。

    Infrared absorption spectra of naphthalene in supercritical carbon dioxide (CO2) solution of various concentrations were measured at 318.15 K and various pressures. The molar absorption coefficient of naphthalene in supercritical CO_2 was found to be dependent on the density of CO_2. As the density of CO_2 increased, a red shift of peak wavenumber of C-C vibration (quadrant stretching) and decrease in FWHM (full width at half maximum)of infrared absorption spectra were observed. This suggests that the molecular motion (vibration and rotation) of naphthalene in supercritical CO_2 was affected by the fluid density. Dimerization of Benzoic acid and tautomerization of 2,4-pemtanedione via hydrogen bonding in supercritical CO2 was also measured using FTIR spectroscopy. The concentrations of monomer and dimer of benzoic acid were determined from absorbance data and Beer-Lambert's law. It was found that the equilibrium constants were dependent on the density and the dimerization equilibrium was shifted to monomeric form at higher densities. The tautomeric equilibrium between keto form (dipole moment: 4D) and enol form (dipole moment: 3D) of 2,4-pentanedione (acetylacetone) was shifted to polar keto form as the density of CO_2 increased, which indicated that the quadrupole moment of CO_2 provided slight polarity and played an important role in the tautomerization of 2,4-pentanedione in supercritical CO_2. MD simulation for LJ fluids indicated that the stability of clusters was strongly influenced be the parameter-epsilon and cluster size was by the parameter-sigma.

    高分子のゾル-ゲル転移は、その際のレオロジ-特性の大きな変化を利用し、多くの化学製品に利用されている。近年ではこの転移を2次相転移現象と捉え、転移の際の巨視的物性の変化を普遍的に記述しようとする動きがある。スケ-リング則はその一つ手段として、適用性が検討されてきたが、電解質高分子系に対する適用例は僅少である。本研究では電解質高分子として電解質多糖類に注目し、種々の金属塩を添加した際のゾル-ゲル転移についてスケ-リング則適用性を検討し、さらに錯体構造とレオロジ-特性の関連性についても言及した。電解質多糖としてはグルロン酸Naとマンヌロン酸Naの共重合体であるアルギン酸Na及びガラクツロン酸Naの重合体であるペクチン酸Na、金属塩としてはCa^<2+>、Cu^<2+>、Co^<2+>等の塩化物を用いた。はじめにこれらの金属塩を添加した際の粘度の変化を調べた。アルギン酸Naに対してはCuCa、Coの順にゲルを化し、一方ペクチン酸Naに対してはCa、CuCoの順にゲル化する結果となり、ゲル化能の序列に相違が認められた。そこで^<13>CーNMRにより金属イオンの結合部位を調べたところ、Caはグルロン酸及びガラクツロン酸に選択的に配位し、Cuは糖鎖に選択性のないカルボキシル基への配位が明らかになった。従って、この微視的な錯体構造を考慮するによって、ゲル化能の相違が説明されることがわかった。またゲル化点近傍における粘度の変化に対してスケ-リング則の適用を試みたところ、その適用性が認められ、臨界指数はいずれも1.0±0.3程度の値が得られた。そこでゲル化の機構の異なる他の系に対する粘度の臨界指数の報告例と比較したところ、同程度の値となることが見いだされた。さらにゾル-ゲル転移におけるもう1つの巨視的物性である弾性率指数に対しても比較を行ったところ、同様な結果が得られ、臨界指数は普遍的な値を有することが示唆された。

    テトラアルコキシシランの溶液重合により得られる単分散性シリカ粒子は、高機能性セラミックス材料の前駆体として様々な応用が期待されている。そのためには生成するシリカ粒子の粒径分布を十分に把握する必要があり、近年、粒子生成機構に関して精力的な研究が行われている。その結果、シリカ粒子生成は粒子核生成及び粒子成長過程よりなることが定説となっているが、多くは定性的な報告に留まっている。特に粒子成長過程に対しては、反応律速及び拡散律速説が提案されており、その結論は得られていないのが現状である。 本研究では、このような現状を踏まえ、生成粒子の粒径制御法を確立することを目的として、テトラエトキシシラン(TEOS)溶液から生成する粒子の成長機構に対して定量的な検討を行った。実験では、まずはじめにモノマ-濃度と生成粒子の粒径分布の関係を調べ、粒子成長過程において粒子凝集が生じない粒径分布の狭い単分散粒子が生成する濃度領域を求めた。次にこの濃度領域内で予め調製した粒径の異なる2種類の単分散シリカ粒子を含むゾルにTEOSを添加し、それぞれの粒径の経時変化を調べた。その結果、粒径の増分は互いに等しいことがわかった。そこで粒子成長速度の粒径依存性について解析したところ、粒子成長速度は粒子半径の概ね2.0乗に比例することがことが判明し、粒子成長速度は粒子表面積に依存する反応律速の可能性が示唆された。以上から本測定を様々な条件下で行い、デ-タの蓄積を行った後、ポピュレ-ションバランス法を適用すれば、粒子成長機構の定量化が可能なものと思われる。

    水溶性高分子を架橋したハイドロゲルの体積相転移は温度、溶媒組成、イオン強度等のゲルの周りの様々な環境の変化により引き起こされ、これにより種々の物性が不連続的に大幅に変化する。このためスイッチ機能性材料として様々な応用が期待されているが、そのためには相転移のパタ-ンとその速度並びにゲル内での物質移動速度の解明が不可欠である。そこで本研究では、ゲルの相転移に関する平衡及び速度論に関するこれらの基本的問題を分子設計の見地から明確にすることを試みた。 非イオン性のNーイソプロピルアクリルアミド(NIPA)ゲルを用いて種々の有機溶媒中で膨潤平衡を測定した。膨潤体積は溶媒種に大きく依存し、溶解度パラメ-タを用いてある程度相関されることが判明した。また、NIPAゲルのN置換基をnープロピル基(NNPA)およびシクロプロピル基(NCPA)に換えたゲルの膨潤平衡を測定したところ、NNPA→NIPA→NCPAとN置換基の広がりの減少とともに転移温度が上昇し、NCPAでは連続的な変化となった。また、NIPAとNNPAゲルについて準弾性光散乱により相転移の動的過程を測定し、見かけの拡散系数はNNPAがNIPAより大きな値を示した。これらの結果は、疎水性置換基の広がりの減少とともに、疎水性相互作用の駆動力が小さくなることに起因すると考えられる。 次に、荷電ゲルを対象として荷電基濃度の高い数種のゲルを合成し、外部溶液のイオン強度と膨潤平衡の関係を検討した。疎水性の大きなスチレン系のゲルでは外部溶液のイオン強度の増加に伴う荷電基の解離性の減少により不連続な収縮がみられたが、親水性のアクリルアミド系ゲルではその収縮は連続的であった。これは、疎水性会合による凝集力と荷電基間の静電反発力のバランスが荷電基の解離状態により変化することに起因するためと推定された。

    水溶性高分子を架橋することによって得られるヒドロゲルは、溶液中において温度や溶媒組成を変化させることにより、その体積が100倍〜1000倍変化す、いわゆる相転移現象を発現する。この特性の応用法としては種々のものが考えられるが、その一つとして、スイッチ機能を有する分離膜がある。本研究では、ゲルの機械的強度に劣る点を無機多孔体との化学結合による複合化法を用いて克服し、その透過特性を検討した。実験に用いたゲルは、溶媒組成によって相転移を起こすアクリルアミド/アクリル酸共重合体ゲルと、温度変化によって相転移を起こすN-イソプロピルアクリルアミドゲルの2種類である。無機多孔体としては多孔質ガラスを用いた。まず、2種類の複合膜について、相転移前後の溶液透過特性を調べ、塊状ゲルの膨潤実験と比較した。その結果、両者とも塊状ゲルが収縮状態にある条件における透過係数が、膨潤状態にある証券の場合に比較して、100倍以上大きくなることがわかった。また、担体の細孔径は透過特性の変化に影響せず、透過特性を支配するものはゲルの性質であることがわかった。さらに、相転移前後の分画分子量の変化を調べたところ、透過係数が大きい条件では分画分子量が大きく、透過係数が小さい条件の50〜100倍であった。また、透過液と供給液の溶媒組成には変化がなく、透過係数は圧力の一次に比例した。以上のことから、ゲル膜の透過機構は、細孔理論によって取り扱えることが示唆された。細孔理論に基づく理論計算の結果、分画曲線の推算結果は、実験結果と良好に一致した。続いて、より詳細に透過機構を検討するために、ゲル膜中のトリチウムの拡散実験をおこなった。その結果、実験結果を細孔理論に基づいて解析すると、ゲル膜の存在する細孔は、ゲルが膨潤状態から収縮状態に転移すると、細孔半径が約5倍になると共に、細孔数は逆に1/50〜1/100程度に少なくなることがわかった。

    水溶性高分子を架橋することによって得られるヒドロゲルは, 外部条件の微小な変化によってその体積が大きく変化する. この体積相転移現象を利用すれば, ゲルをアクチュエイターやセンサー等へ応用することが可能である. 本研究ではゲルの体積相転移現象を支配する因子を明確にし, ゲルの分子設計論を確立することを目的とした. 現在までに体積相転移が報告されているのは, 全てが水を含む相互作用が強い系である. このことより, 本研究では, ゲルの相転移現象を支配する因子は高分子-水間, あるいは溶媒分子同士の水素結合であると推論し, 以下のような実験を行った. 実験に用いたのはアクリルアミド/アクリル酸共重合体ゲルである. まずはじめに, 従来からこの系について報告されているアセトン水溶液の他に, メタノール, エタノール, イソプロパノールの各水溶液に対する相転移挙動を観察した. その結果, 溶媒により相転移点が異なり, さらに転移点とアルコールの水素結合性には明かな相関がみられた. これは, 溶媒である水とアルコール間の相互作用がアルコールあるいは水と高分子の相互作用に比較して大きく, そのため溶媒全体として水素結合能力が変化し, ゲル中の高分子鎖間に一般に疎水性相互作用と呼ばれる効果が発現したためと思われる. この考えに従うと, 溶媒-高分子間の相互作用より溶媒分子間の相互作用が強い溶媒を用いた時には, 疎水性相互作用と類似の疎液性相互作用と呼ばれる現象が起こるはずである. そこで次に, 水と非常に強い相互作用をするDMSOを加えてゲルの挙動を観察した. その結果, 疎液性相互作用と思われる現象を確認できた. 以上よりゲルの相移転を支配する最も大きな因子は, 系内に存在する水素結合であると結論した. また, ゲルの電気化学ポテンシャルを調べる前段階としてゲル中の非イオン性物質の透過現象を観察したが, ゲル中への特別な取り込み現象は観察されなかった.
