摘要
建立了用pH法测定离子交换树脂表面酸性的分析方法。pH法测得的结果能和超声电导滴定法的结果相一致。用所测得的pH值表征离子交换树脂对乙酸和丁醇液相酯化反应的催化活性，能取得满意的结果。该方法是一种简便、迅速、可靠的测定离子交换树脂表面酸性的分析方法。
A new pH method for determining surface acidity of ion exchange resin has been established.Results obtained from pH method can be compared with those obtained from UCT method. Re-sults also show a better correlation between the esterification catalytic activity of ion exchangeresin and the pH value measured by this new method. The pH method is a simple, quick and reli-able method for determining the surface acidity of ion exchange resin.
