正负离子表面活性剂混合体系中季铵盐的测定

Determination of Quaternary Ammonium Salt in Mixed System of Cationic and Anionic Surfactant

使用四苯硼化钠重量法，测定了由Ｃ１２Ｈ２５（ＣＨ３）３ＮＢｒ和Ｃ１１Ｈ２３ＣＯＯＮａ组成的正负离子表面活性剂混合体系中的季铵盐。阐述了该方法的原理及操作。

The Quaternary Ammonium salt in mixed system of cationic and anionic surfactant which is made from C 12 H 25 (CH 3) 3NBr and C 11 H 23 COONa has been determined by using TBN weight method. The principle and operation have been introduced, precise measuring conditions have been studied.
