用两相滴定法考察了伯胺Ｎ１９２３在煤油、氯仿、四氯化碳、甲苯、１，２－二氯乙烷和甲基异丁基酮等稀释剂中对盐酸的萃取，提出了处理萃取平衡的数学方法，观察到伯胺Ｎ１９２３与ＨＣｌ形成的铵盐萃合物在不同稀释剂中存在不同程度的聚合，并确定了聚合度，讨论了稀释剂极性对铵盐聚合度的影响，认为铵盐的这种聚合实际上是它在有机溶剂中形成了反相胶团，其间的作用力可认为是“范德华力”。
A two-phase titration method was used to study the extraction of hydrochloric acid from the primary amine N1923 in kerosene, chloroform, carbon tetrachloride, toluene, 1,2-dichloroethane and methyl isobutyl ketone, Equilibrium mathematical method. It was observed that the ammonium salt complex formed by the primary amine N1923 and HCl had different degrees of polymerization in different diluents, and the degree of polymerization was determined. The influence of the diluent polarity on the degree of polymerization of the ammonium salt was also discussed. It is believed that this polymerization of an ammonium salt actually means that it forms an inverse micelle in an organic solvent, and the acting force therebetween can be considered as “van der Waals forces.”
