介绍了以氨基磺酸为固体催化剂,由乙酸、正丁醇为原料催化合成乙酸正丁酯的方法,根据正交试验结果确定了工艺指标,选定的优化条件为:催化剂用量为乙酸用量的5％,反应时间2H,酸醇摩尔比1:1.4,反应温度为回流温度.在最佳反应条件下,乙酸正丁酯的转化率达98.88％.“,”Synthesizing method of n - bytyl acetate from acetic acid and n - butyl alcohol catalyzed by aminosulfon- ic acid is introduced. The process index is detemined by the test result according to optimum seeking method of cross de- sign, the optimum conditions are selected as following: the weight of catalyst was 5%of the weight of acetic acid, the mo- lar ratio of acid with alohol was 1: 1 .4.and tne reaction the was 2h.the esteification rate is 98.88%under this condi- tion.
