The acetylation of glycerol was carried out over dodecatungstophosphoric acid (PW) supported on activated carbon, being the monoacetin, diacetin and triacetin the reaction products.A series of catalysts, with different heteropolyacid loading (from 3.5 to 6.5wt.%), were prepared. It was observed that the catalytic activity increases with the amount of PW immobilized on the activated carbon, being the...
A micellar heteropolyacids (HPAs) catalyst had been prepared using surfactant cetyltrimethyl ammonium bromide (CTAB) and H 3 PW 12 O 40 as precursors. These micellar [C 16 H 33 N(CH 3 ) 3 ] x H 3−x PW 12 O 40 had been characterized to be micellar structure and the catalytic activity was evaluated by the hydrolysis...
