摘　　要：首次以磷酸二氢钠作为催化剂合成了乙酸丁酯、己酸异戊酯、乙酸异戊酯、乳酸乙酯、乳酸异戊酯,并对酯化反应中的催化剂用量、醇酸摩尔比、回流时间以及催化剂的重复使用等情况进行了优化探讨,取得了较为满意的效果.We have synthesized the Acetic acid butyl ester, Isoamyl caproate, Isoamyl acetate, Ethyl lactate and the Isoamyl lactate by using the Sodium Dihydrogen Phosphate as a catalyst for the first time. The influenceable factors such as amount of the catalyst, molar ratio of alcohol to acid, reaction time and the situation of the catalyst to be recovered are discussed in this paper. And finally we have a satisfying result.
