摘　　要：在硫酸盐复合催化剂存在的条件下,由正丁醇和对羟基苯甲酸高收率合成了的对羟基苯甲酸正丁酯。本文研究了硫酸盐复合催化剂用量、正丁醇用量和反应的时间,带水剂的选择等因素对催化合成对羟基苯甲酸正丁酯收率的影响。实验结果表明,当正丁醇与对羟基苯甲酸摩尔比为0.05∶0.12和复合硫酸盐n(Fe2(SO4)3)∶n(K2SO4)为3.5∶1、带水剂6m L时,回流反应分水240min,酯收率为93.32%,为最佳反应条件。In this paper, it studies dosage of composite inorganic salts catalyst, n-butyl alcohol dosage and re- sponse time, with admixture of select catalytic synthesis of n-butyl p-hydroxybenzoate and other factors on the yield effects under conditions of water combined with composite inorganic salts catalyst, n-butyl alcohol and p-hy- droxybenzoic acid by high-yield synthesis of n-butyl p-hydroxybenzoate. Experimental results demonstrate that ester yields was up to 9332% for the best conditions, when n-butyl alcohol：p-hydroxybenzoic acid mole ratio of 0.05：0.12 and composite inorganic salts is n（Fe2SO4）3） ： n（K2SO4）= 3.5：1, 6mL reaction returning water, reaction time 240 min.
