摘　　要：系统研究了几种常见硫酸盐作催化剂催化合成对羟基苯甲酸丁酯。结果表明,酸式KHSO_4催化活性最高,酯产率达到96.8%,具有Lewis酸性质的硫酸盐催化效果适中,酯化产率68.6～82.4%。The synthesis of butyl p-hydroxybenzoate with sulfate as catalysts was studied systematically. The result indicated that the catalytic activity of potassium hydrogen sulfate was the tallest, and the yield of butyl p-hydroxybenzoate was 96.8 %. The activity of sulfate containing Lewis acids was moderate and the yield of butyl p-hydroxybenzoate was 68.6 %-82.4 %.
