磷钼杂多酸银盐催化合成醋酸异戊酯的研究

Study on the Synthesis of Isobutyl Acetate Catalyzed by Silver Phosphomolybdate Heteropolyacid

本文以磷钼杂多酸银盐为催化剂，对醋酸异戊酯的合成反应进行了研究，探讨了催化剂用量、醇酸摩尔比、反应时间对酯产率的影响。结果表明：在异戊醇用量为０．２５ｍｏｌ的情况下，以环已烷为带水剂，用磷钼杂多酸银盐为催化剂，催化剂用量为 １．５ｇ，醇酸摩尔比为１：１．４，在回流温度下反应２小时后，再用分水装置反应１小时，酯产率达９２．８％。

This paper studied the synthesis of isobutyl acetate using silver phospho molybdate heteroployacid as catalyst. The effects of the amount of catalyst, the ratio of isobutyl alcohol and acetic acid, and the reacting time was investigated. The optimum reac- tion condition was obtained and the yield of the esterification is reaching 92. 8 %
