氯化铁催化合成肉桂酸正丙酯

Catalytic synthesis of n propyl cinnamate with ferric chloride

利用氯化铁为催化剂使肉桂酸和正丙醇酯化合成了肉桂酸正丙酯，其优化条件为ｎ（肉桂酸）∶ｎ（正丙酸）∶ｎ（Ｆｅ２Ｃｌ３·６Ｈ２Ｏ）＝１∶１０∶０．１，回流反应时间为５ｈ，产品收率９５％以上。

The n propyl cinnamate was synthesized by the esterification of cinnamic acid and n propyl alcohol in presence of FeCl 3 ·6H 2O catalyst. The results showed that the optimum conditions were as follows: molar ratio of cinnamic acid, n propyl alcohol and FeCl 3 ·6H 2O was 1∶10∶0 1 with 5 reflux reacting hours and the yield of esters was over 95%.
