本文比较了1-苯基,3-甲基,4-三氟乙酰吡唑酮(5)(代号为HAPZ-8113F,以HA表示)与多种多碳亚砜和双亚砜(以S表示)对于三价铈的协同萃取效应,以二辛基亚砜的协萃能力为最高。并进一步研究了以二辛基亚砜为中性萃取剂,在硝酸和盐酸体系申,和HAPZ-8113F协同萃取Ce(Ⅲ)时的混合萃合物组成。它们分别是:CeAs和CeA_3·NO_3·S以及CeA_2·Cl·HA和CeA_3·Cl·S。从归一化标绘图中推算了各有关的平衡常数。还制得了HAPZ-8113F与钕的固体萃合物及HAPZ-8113F、二甲基亚砜与钕的固体协车合物。它们的组成分别为NdA_3·HA和NdA_3·S。
In this paper, we compared 1-phenyl, 3-methyl, 4-trifluoroacetylpyrazolone (5) (codenamed HAPZ-8113F, HA) with various polysulfoxides and sulfoxides For the synergistic extraction effect of trivalent cerium, the synergistic extraction capacity of dioctyl sulfoxide was the highest. In addition, the composition of the mixed extracts of Ce (Ⅲ) with HAPZ-8113F and HAPZ-8113F in the presence of dioctyl sulfoxide as neutral extractant was studied in nitric acid and hydrochloric acid systems. They are: CeAs and CeA_3 · NO_3 · S and CeA_2 · Cl · HA and CeA_3 · Cl · S. The relevant equilibrium constants are derived from the normalized plots. A solid complex of HAPZ-8113F with neodymium and a solid complex of HAPZ-8113F, dimethylsulfoxide and neodymium were also prepared. They are composed of NdA_3 · HA and NdA_3 · S, respectively.
