摘要
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。
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.
