摘　　要：通过取代反应,合成了对叔丁基杯[4]、[6]芳烃磷氧衍生物,并对其进行红外、1 H和13 C核磁共振表征。考察了pH值、萃取剂浓度、萃取时间、萃取温度对杯芳烃及其磷氧衍生物萃取U(Ⅵ)的影响。结果表明,杯[6]芳烃对U(Ⅵ)的萃取效果优于杯[4]芳烃,杯芳烃磷氧衍生物对U(Ⅵ)的萃取效果优于杯芳烃,在同样的实验条件下,杯芳烃磷氧衍生物对U(Ⅵ)的萃取率比杯芳烃分别提高了36.49%和37.61%。The p-tert-butylealix[4] arene phosphinoxide derivatives and p-tert-butylealix[6]- arene phosphinoxide derivatives were synthesized by substitution reaction. IR, 1 H NMR and ^13C NMR were used to characterize the compounds. The influences of pH, concentration of extractant, extraction time and temperature on the calixarene and its phosphinoxide derivatives＇ extraction of U（Ⅵ） were investigated. The results U（Ⅵ） by p-tert-butylcalix[6]arene is higher than p-tert-b show that the extraction utylcalix[4]arene, meanw extraction efficiencies of U（Ⅵ） by the calixarene phosphinoxide the extraction efficiencies of U（Ⅵ） by calixarenes. Compared wi effect of hile, the derivatives are higher than th calixarenes, the calixareno phosphinoxide derivatives＇ extraction efficiencies of U（Ⅵ） are increased by 36. 49% and 37.61 % respectively under the same condition.
