电化学调价制备2AF Ⅰ.二甲基羟胺和甲基肼的电解氧化

Preparation 2AF Solution by Electrochemical Method Ⅰ. Electrooxidation of Methyl Hydrazine and N, N Dimethylhydroxylamine

摘要: 为将电化学应用于先进后处理流程中的1BP调价制备2AF，采用循环伏安法研究了甲基肼和二甲基羟胺的电化学行为。使用无隔膜的电解池，以钛基镀铂电极为阳极，以钛电极为阴极，在恒电流的条件下进行了电解实验。研究表明，甲基肼在阳极被直接电解氧化；甲基肼被完全破坏后，二甲基羟胺在阴极发生间接的氧化反应。

Abstract: In order to electrooxidate 1BP to preparate 2AF solution in advanced PUREX process, electrochemical behaviors of methyl hydrazine (MMH) and N, N-dimethylhydroxylamine (DMHAN) were studied by cyclic voltammetry. In addition, electrolytic experiments were carried out with platinum as anode and titanium as cathode at constant current in electrolytic cell without membrane. In nitric acid medium, after MMH is oxidated at anode, DMHAN is indirectly oxidated by nitrous acid at cathode.
