聚氯乙烯-三氯化铁的催化酯化作用

CATALYTIC ESTERIFICATION BY POLYMER PROTECTED CATALYST PVC-FeCI_3

本文首次报导了用高分子催化剂聚氯乙烯-三氯化铁催化羧酸和醇的酯化作用,探讨了合成乙酸正丁酯的条件,应用此催化剂制备了乙酸、丙酸、丁酸等11种酯,其收率达80～91%。

This paper report the study on the polymer protected catalyst Polyvinyl Chlo-ride-Ferric Chloride(PVC-FeCl_3)used in the esterification of carboxylic acids andalcohols.This paper deals with the coditions in synthesis on n-butyl acetate cata-lyzed with PVC-FeCl_3.The PVC-FeCl_3 was used as the catalyst for preparing 11esters of acetic acid,propionic acid,butyric acid with the yields 80～91%.
