摘要
采用循环伏安(CV)法确定了草酸可以还原为乙醇酸,以铅作阴极材料的阳离子交换膜电解槽,电解草酸研制乙醇酸,并且以电流密度、电量、温度和电解液的流速做了4因素4水平的正交实验,得出了最佳工艺条件,产率达88%以上.

Abstract:
The feasible from oxalic acid electrochemical reduction to glycollic acid by cyclic voltammetry. Glycollic acid was prepared via oxalic acid by Pb cathode and cation exchange membrane under current density,electric quantity,temperature,velocity of electrolyte flow.Optimal operating conditions were obtained.The yield was over 88%.
