Abstract

Use of Tungstophosphoric acid(TPA) catalyst supported on activated carbon and catalytic on the esterification of isobutyl acetate was studied.The experiment has mild reaction conditions,a fast speed and high productive rate.Inquiry into and find out the best condition.The optimized conditions were as follows:the mole ratio of alcohol to acid was 1∶1.6,the mass ratio of catalyst 7.23%(based on the total mass of reactants),and the reaction time was 100 min.The chemical yield was 91.28%.
