摘要
在酸强度Ｈａｍｍｅｔ函数值Ｈ０为＋５．０～－８．２范围的环己烷溶液中利用胺滴定法观察Ｈａｍｍｅｔ指示剂吸附的颜色变化．选用ＰＫａ值不同的几种指示剂，测出不同酸强度下各种固体催化剂的酸量，作出了酸强度分布曲线。
The colour change of the Hammett indicator adsorbed in the cydohexane solutions with H 0 values in the range of +5.0～-8.2 was observed by means of the amine titration mothod. By using Hammett indicators with different PK a values, the distribution curves of the acid strength as the function of acid quantity were determined and the behaviour of the indicator was discussed.
