摘要: <正> 4,4’-癸二酰-双-(1-苯基-3-甲基-5-吡唑啉酮)(以下简称萃取剂Ⅰ)是新近合成的一系列4-酰基吡唑啉酮类螯合萃取剂中的一种,其结构式如图1所示。 本文研究了它对铀(Ⅵ)的萃取作用机理,离析了固体萃合物,并对萃合物的组成与结构进行了元素分析、质谱、热重、差热、红外光谱和~1H核磁共振等分析测定。Abstract: 4,4'-decanedioyl-bis-(1-phenyl-3-methyl-5-pyrazolone) is one of a series of 1-phenyl-3-methyl-4-acyl-pyrazolones chelate extractants synthesized recently.In this paper, the mechanism by which the chelating agent extracts the uranyl ion is studied. The solid extracted complex is isolated from the solution. The composition and the structure of the solid compound are studied by elemental analyse, TG, DTA, IR, 1H NMR and its molecular weight is determined using mass spectra.
