摘要
用非光气法合成了萃取剂二(六氢吡啶) 1 甲酮,以三氯甲烷为稀释剂.研究了水相硝酸浓度、萃取剂浓度、盐析剂浓度、相比对其萃取铀 和钍 分配比的影响.结果表明,对铀的萃取规律类似于TBP,萃取能力高于TBP,铀的溶剂化数均为 2;在实验条件下对钍基本不萃取,表明在铀
Di-piperidin-1-yl-methanone was synthesized by the means of 'nonphosgene'. The effects of the density of nitric acid solution, extractant and salting-out agent and salting-out agent's phaseratio are also studied on the extraction ratio of dioxouranium? and thorium?, with Di-piperidin-1-yl-methanone(chloroform) as the thinner. The extraction laws of dioxouranium? is similar to that by tributyl-phosphate(TBP), with higher extracting ability than that of TBP. The solvation number to dioxouranium is 2. In the experiment, the extraction of thorium nitrate rarely happens, which shows that dioxouranium and thorium have great potential in application.
