摘　　要：以磷钼杂多酸为催化剂,以乙醇和乙酸为原料合成乙酸乙酯。经实验确定了最佳反应条件:酸醇比为2.5:1—3.0:1,磷钼酸用量为酸质量的2.5％—3.0%,反应时间为4.5 h,酯化率达94％以上。It has shown the method of synthesis of olybdophosphoric acid. Studied the synthesis of ethyl acetate with ethanol and acetic acid as raw material , olybdophosphoric acid as catalysts. The experimental results indicate the optimum condition as follows: the ratio of acid to alcohol is 2.5:1-3.0:1,the quantity of catalystis 2.5%-3.0% of the quantity of acid, the time of reaction is 4.5 h, the rate of production is 94%.The catalysts could be reused 6 times, and the activity dropped a little.
