摘要: 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”.

Abstract: The extraction equilibria of hydrochloric acid with primary amine N1923 in various diluents were studied by means of two-phase titration at 298 K.The results show that the aggregation of N1923 salts is decreased with the diluent polarity increasing.It may be considered that the interaction among aggregated amine salt molecules is just Vander Waal's force.
