摘要
以正丁酸和正丁醇为原料,采用活性炭固载对甲苯磺酸催化合成丁酸丁酯。考察了酸醇摩尔比、催化剂用量、反应时间和催化剂重复使用次数对酯化率的影响,确定了最佳合成条件:醇酸摩尔比1∶1.3,催化剂用量2.5%(以正丁酸为基准),反应时间70 min,酯化率达97.8%。
Butyl butyrate was synthesized with butyric acid and butyl alcohol as raw materils and using p-toluene sulphonic acid supported on active carbon as catalyet. The inflencing factors were studied and the optimum conditions of synthesis were determined: molar ratio of alcohol to acid is 1:1.3, amount of catalyst is 2.5%, reaction time is 70 min, the yield of esterification is up to 97. 8%.
