摘　　要：用磷钨、硅钨杂多酸为催化剂研究了邻羟基苯甲酸异戊酯的合成．考察了酸醇比、反应时间和催化剂用量等反应条件对收率的影响．该催化剂与硫酸、盐酸催化剂相比，不仅选择性好，收率能达到用硫酸催化的水平，而且后处理工序简单、催化剂能重复使用．The sy nthesis of isoamyl 2 hydroxybenzoate with heteropoly acid catalysts has been investigated. The reaction conditions, such as the ratio of alcohol to acid, reaction temperature, reaction time, catalyst weight used etc., have been examined. The reaction yield can be obtained as high as that with H 2SO 4 and the catalysts can be used repeatedly.
