The catalytic activity of resin 732 is higher than D72 when the molar ratio of acetic acid and butanol is 1 : 1 . 2 and catalyst is 35g per mol acetic acid. And the selectivity, stability and lifetime of resin 732 were more superior.

• 在醋酸与丁醇的摩尔比为1：1.；2和催化剂加入量为36克/mol醋酸的情况下，732树脂显示了高的催化活性和好的选择性，且催化活性稳定，使用寿命长，是较好的液固相酯化催化剂之一。
