摘要/Abstract

摘要： 1-苯基-3-甲基-4-苯甲酰基-吡啉酮-5(简称PMBP,本文用A表示)作为金属离子的螯合萃取剂早巳广泛应用,其与稀土离子形成的固态配合物也已报道了几十种,但Ce(Ⅳ)的加合物CeA₄·L(L=Dipy,Phen,Tbpo,Tppo)未见报道,我们合成了上述加合物,对它们作了IR、HNMR、UV和热谱等研究。

Abstract: The coordination compound of cerium(Ⅳ) with PMBP(1-phenyl-3-methyl-4-benzoyl-pyrazolone-5), Ce(Ⅳ)A₄(A:PMBP), and its adducts, CeA₄·L(L=2, 2-dipyridine (Dipy), 1,10-phen-anthroline(Phen), tri-n-butylphosphine oxide(Tbpo) and triphenylphosphine oxide(Tppo) respectively) have been prepared. The molar conductiveties,thermogravimetric curves,IRspectra, electronic spectra and ¹H-NMR spectra were examined. These desired adducts, CeA₄·L, were confirmed by the above experimental data. The order of thermostability of adducts is CeA₄·Phen> CeA₄·Dipy>CeA₄·Tbpo≈CeA₄·Tppo.
