非离子表面活性剂 浊点指数的测定 容量法

[中文适用范围]： 测定是通过在30摄氏度下将蒸馏水加入到表面活性剂的丙醇溶液中直至出现混浊来进行的。 浊点指数的测定提供了一种表征弱烷氧基化衍生物及其烃疏水基团的方法。 这种简单而快速的测量是检查用于磺化等的非离子衍生物的烷氧基化水平的一种有价值的方法。 [外文原描述]： The determination is carried out by adding, at 30 degree Celsius, of distilled water to a propanol solution to the surface active agent until the appearance of cloudiness. The determination of the cloud point index provided a way of characterizing weakly alkoxylated derivates and their hydrocarbon hydrophobic groups. This simple and rapid measurement is a valuable means for checking the level of alkoxylation of non-ionic derivatives intended, for example, for sulphonation.
