1-苯基-3-甲基-5-吡唑啉酮(简称PMBP)是萃取镧系、锕系、碱土金属元素的优良萃取剂之一,已广泛应用于多种金属元素的分离提纯。但是,用它萃取一些配位数较高的金属离子时,常常由于水分子参与配位而影响萃取效果。若能在PMBP苯甲酰基的苯环上适当位置引入含有配位杂原子的适当基团势必会对试剂的络合行为产生一定影响。从而有可能筛选出更符合某些特定需要的新试剂。作者在前人工作的基础上合成了两个新化合
1-Phenyl-3-methyl-5-pyrazolone (hereinafter referred to as PMBP) is one of the excellent extractants for extracting lanthanides, actinides and alkaline earth metals and has been widely used for the separation and purification of various metal elements. However, when it is used to extract some metal ions with higher coordination number, the effect of extraction is often affected by the coordination of water molecules. If the PMBP benzoyl in the appropriate position on the benzene ring containing a coordination complex containing atoms will inevitably have a certain influence on the complexation behavior of the reagent. This makes it possible to screen for new reagents that better meet certain needs. Based on the previous work, the author synthesized two new compounds
