1-苯基-3-甲基-4-苯甲酸基吡唑啉酮-5(PMBP)的研究和应用较为广泛,而1-苯基-3-甲基-4-甲酰基吡唑啉酮-5(PMFP)及1-苯基-3-甲基-4-三氟乙酰基吡唑啉酮-5(PMTFP)的研究还很少,尤其对三价钪络合物的研究则未见报导. 本文根据文献[2、3]合成了这两种萃取剂,熔点和元素分析结果与文献值相等,然后测定了两相的分配比,结果如图1所示.1gD～1g[A]图经归一化,求出斜率为3,得出萃合物的组成为S_CA_3,与PMBP萃取S_C(Ⅲ)的萃合物组成相同,但不能像La(Ⅲ)那样
The research and application of 1-phenyl-3-methyl-4-benzoylpyrazolone-5 (PMBP) is more extensive, and 1-phenyl-3-methyl-4-formylpyrazolone -5 (PMFP) and 1-phenyl-3-methyl-4-trifluoroacetylpyrazolone-5 (PMTFP) have been studied very little, especially for the study of trivalent scandium complexes Reported in this paper based on the literature [2,3] synthesized two extractants, melting point and elemental analysis results and literature values equal, and then measured the distribution ratio of the two phases, the results shown in Figure 1. 1gD ~ 1g [A] The normalized figure obtained the slope of 3, obtained the composition of the extract as S_CA_3, which is the same composition as the extract of PMBP extracted S_C (Ⅲ), but not as La (III)
