【摘要】 本文采用电导、pH滴定法研究了乙醇-水溶液中希土与1′-苯基-3′-甲基-5′-氧代吡唑-4′-基乙醛酸（简称H₂A）的配位反应.合成了15种新的希土固态配合物.通过元素分析、化学分析、水份分析确定了配合物的化学组成为RE（HA）₃·nH₂O（RE=Ce、Pr、Sm、Tm、Lu、n=1;RE=La、Nd、Eu、Gd、Tb、Dy、Ho、Er、Yb、Y,n=1-2）.并对配合物的红外光谱、核磁共振谱、热稳定性、紫外光谱、溶解性及摩尔电导进行了测定.更多还原

【Abstract】 This paper is a report on the preparation and properties of the complexes of rare earth with (l’-phenyl-3’-methyl-5’-pyrazolonc-4’-) carbonyl methanoic acid. Compounds with general formulas: RE(HA)3 · nH2O(RE = La, Ce(Ⅲ), Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y. n= 1-2) were obtained and characterized by elemental analysis, chemical analysis, IR, electron spectra, DTA-TG and 1H NMR. All fifteen complexes arc soluble in alcohol, acetone, trichloromethane, etc., insoluble in water, benzene. In atmosphere, these complexes arc stable at room temperature.更多还原
