Glyceryl triacetate was synthesized by using tungstophosphone acid supported on activated carbon. The influences of absorbing quantity of tungstophosphoric acid, ratio of reactants, quantity of catalyst, kind and amount of water carrier were examined. Results show that the activated carbon supported tungstophosphoric acid is a high active and stable catalyst. The yield and purity of product can reach 86.4% and 99.2% separately under the optimized conditions.
