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、1H NMR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、pH1/2和logKex值。

关键词: 苯基甲基双吡唑啉酮, 苯二甲酰化合物, 螯合萃取剂, 合成, 萃取, 铀(Ⅵ)

Abstract: Three new chelating agents of phenylenediacyl bis 1-phenyl-3-methylpyrazol-5-one (PMP) end groups have been synthesized. Their structures have been characterized by elemental analysis,UV,IR,1H NMR and MS spectra. The extraction of U(Ⅵ) with these compounds have been studied.The values of the pH1/2, logKex and chemical composition of the complexes have been obtained by the slope analysis method.

Key words: phenylmethylpyrazolone, phenylenediacyl compound, chelating agent, synthesis, extraction, U( Ⅵ)
