| 摘 要： | 研究了邻甲苯磺酸铜催化苯甲酸和正丁醇的酯化反应，考察了催化剂用量、醇酸摩尔比、反应时间等因素对酯化率的影响；找到了较佳的反应条件：苯甲酸用量为O．167mol，醇酸摩尔比为1．2：1，催化剂用量为1．0％（以苯甲酸的摩尔分数计），反应时间为2．5h，环己烷用量为5mL，在此条件下酯化率可达97．4％。邻甲苯磺酸铜重复使用5次后．其催化活性无明显下降。

| Abstract: | o-Toluenesulfonate was used as catalyst for the esterification of benzoic acid and n-butyl alcohol. Effects of the amount of catalyst, reaction time and the mole ratio of alcohol to acid were inves the mole tigated. The yield was up to 97.4% under the optimum conditions： benzoic acid 0.167 mol, ratio of alcohol to acid 1.2： 1, the amount of catalyst 1.0% （molar percent of benzoic acid）, reaction time for 2.5 h, 5 mL cyclohexane, o-Toluenesulfonate was used repeatedly for 5 times without obvious loss of activity. |
