摘　　要：合成了３个以ＰＭＰ为端基、以苯二甲酰为桥基新螯合萃取剂、用溶剂结晶法分别制备了它们的烯醇体和酮体，通过元素分析、ＵＶ、ＩＲ、￣１ＨＮＭＲ和ＭＳ对其进行了表征，用斜率法研究了新试剂对水相中铀（Ⅵ）离子的萃取行为，求出了萃合物组成、ｐＨ＿（１／２）和ｌｏｇＫ＿（ｅｘ）值。Three new chelating agents of phenylenediacyl bis 1-phenyl-3-methylpyrazol-5-one(PMP ) end groups have been synthesized. Their structures have been characterized byelemental analysis,UV,IR,￣1H NMR and MS spectra. The extraction of U(Ⅵ)with thesecompounds have been studied.The values of the pH_(1/2), logK_(ex)and chemical composition ofthe complexes have been obtained by the slope analysis method.
