3 Liquid-phase Organic Reactions over Silica-occluded H3PWj2O40 [Pg.102]

Silica-occluded H3PW12O40 can be used as an insoluble solid-acid catalyst in several liquid-phase reactions such as ester hydrolysis [15c], esterification [15dj, hydration [15d], alkylation of phenol [15d] in polar media, and Friedel-Crafts type alkylation and transalkylation [16] in non polar media.
