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。
The extraction behavior and mechanism of 1-phenyl-3-methyl-4-benzoylpyrazolone-5 (HPMBP) have more comprehensive study on the composition and properties of more than 50 kinds of elements, However, little reports have been reported on the corresponding compounds of the 4-acyl acyl group. It has not been reported for its extraction mechanism with rare earth elements and the preparation of solid complexes. In this paper, the extraction mechanism of rare earth elements La, Nd, Gd, Lu and Y by HPMCP was investigated. The composition of the complexes was calculated by the slope method, the equilibrium reaction of extraction was determined, the equilibrium constants of extraction were calculated and their solid complexes , And its composition and heat spectrum, infrared spectroscopy, nuclear magnetic resonance spectroscopy were studied.
