摘要
本文以三烷基胺(7301)为络合剂,正辛醇、煤油、氯仿、四氯化碳等为稀释剂,测定了络合萃取剂对于对甲基苯磺酸、磺基水杨酸稀溶液的相平衡分配系数,讨论了稀释剂、体系pH值和7301络合剂含量对萃取相平衡分配系数D值的影响,确定了形成的萃合物的组成,
Extraction process based on reversible chemical complexation has high capacity and high selectivity for dilute polar orgnic solution. In this paper, extraction of p-toluene-sulphonic acid, sulphosalicylic acid with a tertiary amine (7301) in octanol, CHCl3, CCl4 or kerosene has been studied. The effects of diluents, pH and concentration of a tertiary amine(7301) on the distribution ratio D have been investigated. The composition of complex has been determined.
