摘要
以乙酸和对甲苯酚为原料，采用活性炭负载对甲苯磺酸作催化剂合成乙酸对甲酚酯。考察了影响反应的因素，实验结果表明酯化反应的最佳条件：乙酸、对甲苯酚、活性碳负载对甲苯磺酸的摩尔比为1：2；0．064，反应温度在130～150℃，反应时间30min，产率可达95．879，5。
P-cresylic acetate was synthesized with acetic acid and p-cresol as raw materils using p-toluene sulphonic acid supported on active carbon as catalyst. The factors of influencing reaction were investigated. Experimental results indicated that the optimum conditions of esterification reaction are：the molar ratio of acetic acid and p cresol and p-toluene sulphonic acid supported on active carbon is 1 ： 2 ： 0. 064, the reaction temperature is 130-150℃,the reaction time is 30min,and the yield up to 95.87%.
