SDK Receives Green & Sustainable Chemistry Award

Showa Denko K.K.
February 26,2007

Showa Denko K.K. (SDK) has received the Minister of Economy, Trade and Industry prize for its development of a green process based on solid heteropolyacid catalysts, together with Professor Toshio Okuhara, Graduate School of Science, Hokkaido University, and Mr. Makoto Misono, President, National Institute of Technology and Evaluation (professor emeritus, Tokyo University).

The prize forms a part of the sixth Green & Sustainable Chemistry (GSC) Award from the GSC Network, which is a council of chemical academic societies, organizations and national research institutes founded in March 2000.

The Network joins in the global GSC movement for sustainable society, contributing to health and environmental safety through the development of innovative chemical technologies. In 2001, the Network began granting GSC awards to organizations and individuals who contributed to the GSC movement. A Minister of Economy, Trade and Industry prize is awarded to honor achievements in industrial technologies.

The solid heteropolyacid, comprising the core of a phosphorus or silicon atom surrounded by twelve units of tungsten oxides, is placed on a porous, chemically stable carrier. Using this innovative catalyst, SDK is producing ethyl acetate from ethylene and acetic acid, as well as producing acetic acid by directly oxidizing ethylene.

Through cooperation with academia, SDK has succeeded in improving the catalyst performances and production processes, raising yield and substantially extending the catalyst life. SDK has received the award due to the resource- and energy-saving effects of the new green process technology.

The prize awarding ceremony will be held in Tokyo on March 7.
