摘要

合成了对叔丁基杯［４］芳烃及其衍生物对叔丁基杯［４］芳烃乙酸，研究了对叔丁基杯［４］芳烃乙酸对铀酰离子的萃取。测定了不同酸度和不同萃取剂浓度对分配比的影响。确定其萃合物组成为ＵＯ２Ｈ２Ｌ。求出了萃取反应平衡常数，讨论了萃取机理。

Abstract

The p-tert-butylcalix[4]-arene and p-tert-butylcalix[4]-arene acetate havebeen synthesized. The solvent extraction of uranium(VI ) with p-tert-butylcalix[4]-arene acetate was studied

including the effects of acidity in aqueous phase andconcentration of extractant in organic phase on the distribusion ratio. Theequilibrium constants of the extraction reaction were determined

and the reactionmechanism was discussed.
