Abstract

Freely water-soluble heteropolyacid could be made insoluble either by supporting on active carbon or by forming acidic cesium salts. In addition, 12-tungstophosphoric acid and its acidic cesium salt could be effectively immobilized in silica matrices by means of a sol-gel technique which involves the hydrolysis of ethyl orthosilicate to give insoluble, readily recoverable, and highly active solid acid catalysts for the hydrolysis of ethyl acetate.
