氯化铁催化合成羧酸酯

Catalystic Synthesis of Carboxylic Ester with Ferric Chloride

以氯化铁为催化剂 ,对羧酸酯化反应进行了研究 .考察了反应条件对酯化产率的影响 .结果表明 ,氯化铁具有较高的催化活性 ,是可以代替硫酸的酯化催化剂 .在最佳反应条件下 ,所研究酯的产率达 85 - 97% .

The carboxylic ester was synthesized by using a f er ric chloride as catalyst. The effect of reaction conditions on the yield of carboxylic ester was investigated . Experiment results show that the ferric chloride is more active and under the optimun reaction conditi on the yield is up to 85-97% .Thus the green catalyst may replace sulfur ic acid .
