摘要

通过酰基化、氯化、硫化反应合成了新的酰代吡唑硫酮

即4-（4-甲氧基）-苯甲酰基-2

4-二氢-5-甲基-2-苯基-3H-吡唑硫酮-3（HMBMPPT）。产物的结构用红外、氢核磁共振谱、质谱、元素分析及X射线衍射进行了表征。研究了以氯仿为溶剂HMBMPPT 在硝酸介质中对铀（VI）的萃取行为

考察了稀释剂、萃取剂浓度、酸度、温度及盐析剂浓度对分配比的影响。同时

对萃取配合物的化学组成及萃取机理也进行了分析和讨论。

Abstract

A novel extractant

4-(4-methoxybenzoyl)-2

4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-thione (HMBMPPT) was synthesized. Its composition and structure were confirmed by elemental analysis

mass spectrome-try

1H NMR and X-ray crystal analysis. The extraction of U(VI) with HMBMPPT in chloroform from nitric acid solution was studied including influences of diluents

the salting-out agent concentration

acidity in aqueous phase and extractant concentration in organic phase as well as temperature on the distribution ratio. The chemical composi-tion of extraction complex and the extraction mechanism were also discussed.
