有关伯胺萃取钯(Ⅱ)的动力学研究,尚未见报道。本文用恒界面池搅拌法考察了N1923-正辛烷溶液从氯化物介质中萃取Pd(Ⅱ)时,诸因素的影响,用离子选择电极连续检测萃取过程中水相Pd(Ⅱ)浓度随时间的变化。实验试剂 N1923中国科学院上海有机化学研究所实验厂生产,经减压蒸馏,收集175-205℃/5-10Torr馏分,电位滴定法分析,每克N1923含3.535mmol伯胺,即平均分子量为283,含量>99.7%。0.200mol·dm~-3N1923的正辛烷溶液
Kinetic studies on palladium (Ⅱ) extraction from primary amines have not been reported yet. In this paper, the influence of various factors on the extraction of Pd (Ⅱ) from the chloride medium by N1923-n-octane solution was investigated by the constant interface pool stirring method. The concentration of Pd (Ⅱ) The change. Experimental reagent N1923 Experimental Institute of Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, vacuum distillation, collecting 175-205 ° C / 5-10Torr fraction, potential titration analysis, each gram N1923 containing 3.535mmol primary amine, the average molecular weight of 283, Content> 99.7%. 0.200mol · dm ~ -3N1923 n-octane solution
