和文要約和文要約等以下本編抜粋:1. 研究開発の内容および成果等 (1) 「アクア触媒によるアセトアルデヒド製造プラント排水中の希薄酢酸回収技術」(実施体制:国立大学法人東京大学、昭和電工株式会社) 当初想定していたエステル化/エステル交換プロセスでは、エステル交換工程および精製工程におけるスチームコストが過大であるため、本年度は酢酸濃縮/水中エステル化プロセスの開発に注力した。酢酸濃縮工程においては、酢酸を抽出する抽出液として長鎖アルキルアミンと高級アルコールとの混合物について検討を実施した。
英文要約NEDO project "Development of Fundamental Technologies 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 Technologies for Catalytic Processes Using Aqua and Immobilized Catalysts" and performed the development of fundamental technologies toward industrial processes utilizing seeds technology such as "aqua catalysts" (the catalysts which can function in water) and recyclable polymer-immobilized metal 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), concentration of acetic acid/esterification in water process was examined. By using trioctylamine and lipophilic alcohol, acetic acid was extracted smoothly. Polymer-supported sulfonic acid-catalyzed esterification reaction of aqueous acetic acid and ethanol proceeded in good yield by adding organic solvent. In the sub-theme "Development of Innovative Hydrogenation Reaction System Using Immobilized Catalysts" (Nikko Chemicals Co., Ltd. and the University of Tokyo), large amount (100 kg) of polysilane-supported palladium catalyst was prepared and enough catalytic activity in continuous hydrogenation reactions was obtained. By using larger column reactor (100 mm diameter), quantitative yields could be obtained in several substrates. In the sub-theme "Development of Polymer-supported Metal Catalyst Reagents for Green Process" (Wako Pure Chemical Industries, Ltd. and The University of Tokyo), polymer-incarcerated osmium catalyst (PI Os) which has higher molecular weight was found to improve suppression of osmium leaching (<1%) and could be recycled five times. Application of the catalyst to the reaction for the synthesis of anticancer agent was demonstrated. Other metal catalysts (PI/CB-Au and PI Pt/Au) were also prepared in larger scale (100 g). In the sub-theme "Development of Aqua and Immobilized Catalyst Technique" (The University of Tokyo), several green and efficient catalytic systems were developed such as one-pot sequential reaction process using immobilized catalyst. Molecularly-imprinted ruthenium catalyst was investigated and novel manganese catalyst was developed in the University of Electro-Communications. A model machine for fully-automatic flow system using polymer-supported catalysts were applied to investigation of reaction conditions in hydrogenation reaction in the University of Tokyo and Tokyo Rikakikai Co. Ltd.
