以前に開発した、DBSA触媒は、活性は高いが、水槽への溶出が課題であった。そこで、小林研究室で開発されたエステル化反応を促進する水中固体酸触媒であるALPS(Alkylated Polystyrene-supported Sulfonic Acid)触媒をベースに、製造/精製方法の見直しと、本エステル化反応に対する構造最適化とを実施した。その結果、触媒活性を2倍以上(DBSAと同等)に向上させることに成功した。このときに触媒成分の水層への溶出は無かった。
英文要約NEDO project "Development of Fundamental Techniques for Green-Sustainable Chemical Process"started in 2009. Our group (The University of Tokyo, Showa Denko K.K., Nikko Chemicals Co., Ltd., Wako Pure Chemical Industries, Ltd., the University of Electro-Communications (reconsignment) and Tokyo Rikakikai Co. Ltd. (reconsignment)) has a theme named "Development of Innovative Techniques for Catalytic Processes Using Aqua and Immobilized Catalysts" and performed the development of fundamental techniques toward industrial processes utilizing seeds technique such as "aqua catalysts" (the catalysts which can function in water) and recyclable metal-immobilized catalysts. In the sub-theme "Development of Recovery Method of Organic Compounds from Diluted Aqueous Solution Using Aqua catalysts" (Showa Denko K.K. and The University of Tokyo), by using alkylated polystyrene-supported sulfonic acids or dodecylbenzenesulfonic acid-ammonium salts the esterification reaction proceeded smoothly and the catalyst solubility in aqueous phase could be suppressed. Another process (Concentration of acetic acid/esterificaiton in water) was examined for the purpose of cost-effectiveness. In the sub-theme "Development of Innovative Hydrogenation Reaction System Using Immobilized Catalysts"(Nikko Chemicals Co., Ltd. and the University of Tokyo), the high catalyst turnover (>50000) was obtained in the hydrogenation reaction in the presence of palladium-immobilized catalyst using polysilane and aluminum oxide as supports. The catalytic activity was maintained over 900 hours during the reaction. In the scale-up experiments, a flow reactor that has 50 mm diameter could be applied to this reaction. In the sub-theme "Development of Polymer-supported Metal Catalyst Reagents for Green Process"(Wako Pure Chemical Industries, Ltd. and The University of Tokyo), a series of polymer-incarcerated osmium catalyst (PI Os) developed in the project were found to have high catalytic activity (yield >80%, selectivity >90%, recovery of catalyst >95%, leaching of metal <3%). A large scale asymmetric dihydroxylation reaction using 1 mol olefin afforded the possibility of industrial application of this process. Other metal catalysts (PI/CB-Au and PI Pt/Au) were also developed and 20g scale preparation of the catalysts was attained. In the sub-theme "Development of Aqua and Immobilized Catalyst Technique"(The University of Tokyo), novel aqua and immobilized catalysts were developed and applied to carbon-carbon bond-formation or esterification processes. Molecularly-imprinted Ruthenium catalyst that works in water was developed in the University of Electro-Communications (reconsignment). A model machine for fully-automatic flow system using polymer-supported catalysts were developed and applied to oxidation reaction using molecular oxygen as an oxidant in the University of Tokyo and Tokyo Rikakikai Co. Ltd.(reconsignment).
