1-苯基-3-甲基-七氟丁酰吡唑酮-5(PMHFP)及邻菲咯啉(phen)希土混配配合物的合成及性质研究

STUDY ON THE SYNTHESIS AND PROPERTIES OF THE SOLID COMPLEX COMPOUNDS OF RARE EARTH ELEMENTS WITH 1-PHENYL-3-METHYL-4-HEPTAFLURBUTYRYL-PYRAZOLONE-5 AND 1,10-PHENANTHROLINE

本文在乙醇中合成了PMHFP及phen与希土离子的三元配合物Ln(PMHFP)_3·phen(Ln=La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu,Y).通过化学分析,元素分析及电导分析确定了配合物的组成;研究了配合物的紫外、红光光谱;借助于差热-热重分析仪研究了所有配合物的挥发性质,测定了它们各自的起始挥发温度,探讨了用于希土分析的可能性.

The fifteen volatile complexes of rare earth elements (except Pm) withl-phenyl-3-methyl-4-heptaflurobutyryl-pyrazolone-5(PMHFP) and 1,10-phcnanthrolinc(phcn) have been prepared in the ethanol solution and characterized by elemental analysis; IR and UV spectra, Volatility and thermal stability of the complexes have been studied by thermogravimetric (TG) and differential thermal analysis (DTA).The volatilities of the complexes as the ionic radius of rare earth decrease,with yttrium occupying a place near Nd.
