新席夫碱萃取剂（HPMαFP）_2EN的合成及其在反相纸色谱中应用的研究

Research on synthesis of new Schiff base reagent(HPMαFP)_2EN and its application in reversed-phasepaper chromatography

合成了新席夫碱萃取剂Ｎ，Ｎ’－双［（１－苯基－３－甲基－５－氧－４－吡唑啉基）α－呋喃次甲基］乙二亚胺［（ＨＰＭａＦＰ）_２ＥＮ］。通过元素分析、红外光谱、核磁共振谱、质谱和紫外光谱研究，确定了其结构及有关性质。以这种萃取剂为固定相并采用反相纸层析色谱法首次研究了试剂对稀土离子的分离性能。试剂在ｐＨＯ．２～１．２时，可实现某些多组分混合稀土离子体系的分离。

In this paper a new Schiff base reagent N,N'-bis[(1-phenyl-3-methyl-5-oxo-4-pyra o a-furyl-furylmethylidyne ] ethylenediimine [(HPMaFP)2EN ] hasbeen synthesized. its structure has been confirmed byelemental analysis,IR,NMR and MS. Some propertieswere determined. Its behavior in separating rare earthions has been studied by reversed-phase paper chromatography with (HPMaFP)2EN as stationary phase,acidified NawSO4 solutions as eluents. It has beenshown that this reagent can be applied to the separation of multicomponent rare earth mixtures in the PHrange of 0. 2-1. 2.
