摘要
以十二钨磷酸为催化剂,由对羟基苯甲酸和正丁醇酯化制得对羟基苯甲酸丁酯.考察了各种因素对酯化反应的影响,得到了反应的最佳条件.在最佳工艺条件下,对羟基苯甲酸丁酯的产率可达92%,产品纯度99.4%.
By use of dodecatungstophosphoric acid as catalyst,butyl para hydroxybenzoate was synthesized by esterification of para hydroxybenzoic acid and butyl alcohaol.The optimum reaction conditions were determined.The yield of butyl para hydroxybenzoate can reach 92%,and the purity can reach 99.4%.
