羧酸和醇类酯化反应的高分子载体催化剂
THE POLYMER SUPPORTED CATALYST FOR ESTERIFICATION REACTION of ORGANIC ACID AND ALCOHOL
Abstract
用SnCl4处理过的H型大孔强酸性阳离子交换树脂作为羧酸和醇类酯化的高分子载体催化剂，在正丁醇与乙酸摩尔比1∶1和97~104℃、1.5H条件下，酯化率为9301%和选择性为100%。讨论了催化剂用量、原料摩尔比和不同醇类对酯化率的影响 The polymer supported catalyst was obtained by the cationic exchange resin treated with SnCl 4.Its esteriFication conversion was 93.01% and selectivity was 100% under n C 4H 9OH/CH 3COOH mole ratio 1∶1,97～104℃ and 1.5h.The eFFect of catalyst amount,alcohol/acid mole ratio and variant alcohols on esteriFication conversion was discussed.
