摘要: 1-苯基-3-甲基-4-苯甲酰基吡唑酮-5(HPMBP)对五十多种元素的萃取行为、作用机理以及固态配合物的组成与性质已有较全面的研究,但对四位为己酰基的相应化合物有关报道不多,它与稀土元素的萃取机理以及固态配合物的制备尚未见报道。本文考察了HPMCP对稀土元素La、Nd、Gd、Lu、Y的萃取机理,并用斜率法求出了配合物的组成,确定了萃取平衡反应,计算了萃取平衡常数、合成了它们的固态配合物,并对其组成以及热谱、红外光谱、核磁共振谱等进行了研究。

Abstract: The extraction behavior of rare earths with HPMCP-petroleum ether has been studied. Experimental results showed that rare earth ions as Ln(PMGP)3·HPMCP form were extracted into organic phase. Their extractive constants 1gKwere calculated by the slop method. On the basis of this, their solid complexes were produced. The constitution of solid complexes is Ln(PMCP)3·2H2O. Their spectrum, IRand NMR were also studied.
