摘要
采用一水硫酸氢钠作催化剂 ,合成了肉桂酸乙酯。当醇酸摩尔比为 5∶1,催化剂用量占肉桂酸质量的2 0 % ,反应温度 14 0℃ ,回流时间为 2h时 ,产率可达 91 1%。
Ethyl cinnamate is synthesized by esterification using sodium bisulfate with a water molecule as catalyst.Under the molar ratio of alcohol to acid 5∶1,the amount of catalyst was 20% based on the mass of cinnamic acid,reaction temperature 140 ℃ and reaction time 2 h,the yield was 91.1%.
