摘　　要：以乙酸、苄醇为原料,磷钼酸(HPM)作为催化剂催化合成乙酸苄酯 对催化剂使用的最佳条件和重复使用的效果进行了研究 结果表明:磷钼酸具有很好的催化性能,且当催化剂质量与反应物总质量之比为1.2%、苄醇和乙酸物质的量之比为1∶1.3、反应温度为95℃、反应时间2h时。In this paper, Phospho-molybstic acid(HPM) is used as catalyst, and benzoicalcohol and glacial acetic acid are used to synthesize benzyl acetate .The activity has been studied. The results show that Hhospho-molybstic asid is the best catalysts and the best reaction condition was found .The reaction temprature 95℃,n(alcoho):n(acid)= 1:1.3, reaction time: 2h and the mass ratio of catalysts to general mass reactant are 1.2%. That yield reaches over 90.0%.
