Japanese precious metals manufacturer refocuses

Japanese precious metals producer Tokuriki Honten is refocusing its business to materials for precious metal catalysts and forecasts this sector to increase sales from 30% to 50% of the business by 2005. Tokuriki currently manufactures catalysts via affiliated company Yamato. Brief background detail on Tokuriki is given.

Spacer-modified polymer supports have been synthesized through the polymeric Grignard reagent method. Phosphonium-active sites were then introduced into these supports and the polymer-supported phosphonium salts were used as phase transfer catalysts for the nucleophilic substitution reactions. lnflu

Six organometallic compounds were tested to see if they could behave as phase Summary: transfer catalysts. All of the compounds appeared to catalyze the base hydrolysis of p-nitrophenylacetate in a 2 layer aqueous-organic system. Research on phase transfer catalysis (PTC) has largely been focused on
