摘　　要：本文报道使用一种新的复合型催化剂 (TsOH -PPDS) ,使羧酸和醇快速合成酯的研究结果。使用这种新型催化剂合成了13种酯 ,其催化效果比较好 ,回流时间仅15mim ,最高酯化产率达到92.5 %It is to report that the esters were synthesized with the carboxylic acids and the alcohols rapidly by the new catahyst,which is mixed with TsOH and PPDS. The esters of 13 species were syntheized with the mixed catalyst. The catalytic efficiency of catalyst is a high. The reflux time of a esterfication is 15 min merely,and the best of the yield is 92.5%.
