杯芳烃的配位化学(Ⅸ)──杯芳烃萃取金属的机理

Coordination Chemistry of Calixarenes(Ⅸ)─Extraction Mechanism of Metal Ions with Calixarene

合成了六对叔丁基杯[6]芳烃，八时叔丁基杯[8]芳烃和四甲基羰基甲氧基四对叔丁基杯[4]芳烃，并以杯芳烃进行萃取金属离子的研究．对杯芳烃萃取金属的三种机理进行了探讨，并测出其萃取平衡常数．

In this paper we report that the P- tert - butyl calix[6]arene, P-tert - butyl calix[8]arene and tert- methoxy P- tert- butyl calix[4]arenetetrakone are synthesized, and extraction of metal ions with these threecalixarene were studied. The reaction mechanism of three kinds of extractionmetal ions with calixarene is discussed. The equilibrium constants ofextraction reactions are determined.
