活性炭固载对甲苯磺酸催化合成肉桂酸正丁酯

The Synthesis of n-Butyl Cinnamate Catalyzed by p-Toluenesulfonic Acid Supported on Activated Carbon

研究了用活性炭固载对甲苯磺酸作催化剂催化合成肉桂酸正丁酯。获得了最佳反应条件 :肉桂酸用量为0 .0 2mol时 ,肉桂酸与正丁醇摩尔比为 1∶2 .5 ,催化剂 0 .8g ,反应时间 1h ,在此条件下产率可达 85 .7%。

The synthesis of n-butyl cinnamate catalyzed by p-toluenesulfonic acid supported on activated carbon was investigated. The optimum conditions were as follows: the mol ratio of cinnamic acid and n-butanol was 1:2.5,the amount of the catalyst was 0.8g,the time of the reaction was 1h, when 0.02mol of cinnamic acid was used. Under this condition the yield of n-butyl cinnamate acid was up to 85.7 %.
