| Abstract: | P- toluene sulfonic acid was used as catalyst in catalytic synthesis of sorbic acid ethyl ester. The iulluence of synthesis conditions such as reaction time, molar ratio of reactants, dosage of catalyst was studied. The results show that： the amount of catalyst is 25% of mass of acid alcohol, the molar ratio of acid alcohol to ethanol is 1：5; the reaction time is 3h. Under the conditions above, the yield of acid alcohol is 75.04%, and purity is above 98%. |
