摘要
采用对甲苯磺酸作为催化剂、苯作为带水剂,对肉桂酸和异戊醇的酯化反应进行了研究。在最适宜的实验条件下,该反应可在4h内完成,酯产率达94%以上。该法操作方便,易于工业化生产。
The direct esterification of cinnamic acid with isoamyl alcohol by use of a small amount of p-toluene sulfonic acid as the catalyst and benzene as the water-carrying agent is studied. The esterification can be finished in 4 hours with over 94% yield under the appropriate reaction conditions. This experimental method is convenient and feasible for industrial production.
