摘要: 本文用“萃取-沉淀法”、“水溶液析出法”合成了稀土(Ⅲ)及Ce(Ⅳ)与螫合剂PMHFP的固态络合物。测定了络合物的组成,研究了紫外、红外光谱、热稳定性以及个别络合物作为核磁共振中的化学位移试剂的可能性。

Abstract: The complexes of rare earth elements (except Pm) and 1-phenyl-3-methyl-4-heptaflurobutyryl-pyrazolone-5 have been prepared in solid state and characterized by elemental analysis,infrared and ultraviolet spectra, as well as thermogravimetric (TG) and differential thermal analysis (DTA). Their composition is LnA3·HA (LnA3 for Lu). Besides, the possibility of some other solid complex compounds has also been tried as a shift reagent in nuclear magnetic resonance spectrum.
