A Pronounced Catalytic Activity of an Acidic Cesium Salt of 12-Tungstophosphoric Acid for Ester Decomposition in Solid–liquid System

Abstract
The acidic Cs salt of 12-tungstophosphoric acid (Cs/polyanion = 2.5) was much more active for liquid phase decomposition of cyclohexyl acetate than Nafion, HY-zeolite, H-ZSM-5, Al3+-exchanged montmorillonite, and SO42−/ZrO2.
