八面沸石在精细有机合成中的催化作用研究──XV脱铝超稳Y催化酯化反应

STUDIES ON THE CATALYSIS OF FAUJUSITE IN FINE ORGANIC SYNTHESIS-XV ESTERIFICATION OF CARBOXYLIC ACID WITH ALCOHOL CATALYZED BY DEALUMINATED USY

研究脱铝USY催化羧酸与醇的直接酯化反应，考察了催化剂硅铝比对酯化反应的影响及不同类型酸酶酯化的一般规律．结果表明，脱铝USY是酯化反应的良好催化剂．

In this paper, the direct esterification of carboxylic acid and alcohol by using dealuminated USY as catalyst was studied. The influence of silica/alumina in the catalyst and the general law of esterification were investiguted. The experiminatal results showedthat the dealuminated USY was a good catalyst.
