摘要
报道了经Lewis酸性物质处理的大孔强酸性阳离子交换树脂(Dool-cc)作为乙酸和正丁醇酯化固体酸催化剂的研究结果.应用离子交换法和浸渍法制备催化剂,在醇/酸克分子比1∶1、90~102℃和1.5h的条件下,其酯化活性分别为91.7%和93.1%,酯化选择性达100%,并得出酯化活性随树脂固体表面酸度的提高而增大.
This paper presents the study results of esterification of acetic acid with n butyl alcohol catalyzed by solid acid catalysts which is obtained from the macropopous strongly acidic cationic exchange resin (Dool cc) treated with lewis acidic materials.The ionic exchange technique and the impregnatinal technique were employed to preparing the catalyst and its esterification activity were 91.7% and 93.1% and esterification selectivity was 100%,respectively,under conditions of acid/alcohol mole ratio 1∶1 and l.5h.It was obtained that the esterification activity increased with the increasing the surface acidity of the resin.
