以苯环为桥联新型二酰代双PMP的合成及其对铀(Ⅵ)的萃取行为研究(英文)

Syntheses of New Type Diacyl Bis-PMP Taking Benzen Ring as Bridging Linkage and Studies on the Extraction Behaviors of U(Ⅵ) with These Compounds

以PMP杂环为端基以苯环为桥联设计并合成了三个新的螯合萃取剂,用溶剂结晶法制备了化合物的酮式（a）和烯醇式（b）.通过元素分析、UV、IR、1HNMR和MS对新化合的结构进行了表征,研究了新试剂对铀（Ⅵ）的萃取行为,用斜率分析法求出了萃合物的组成、pH1/2和IgKex值.

In this paper, The syntheses and studies on the extraction to U(Ⅵ) of three new type diacyl bis-PMP chelating agents were reported briefly.
