摘要
用循环伏安法确定了草酸可以还原为乙醇酸,证明了从草酸研制乙醇酸的可行性。工艺采用以铅电极作阴极材料的阳离子交换膜电解槽,电解草酸制备乙醇酸,并以电流密度、电量、温度和电解液的流速作了四因素四水平的正交实验,得出最佳工艺条件为电流密度1400A/m2,电量1 7F/mol,温度40℃,电解液流速0 15m/s,产率达88%以上。
Electroreduction of oxalic acid to glycolic acid was confirmed by cyclic voltammetry.Glycolic acid was prepared from oxalic acid at the Pb cathode in an eletrolytic cell with cationexchange mambrane.By orthogonal experiments the optimal operating conditions were obtained:current density 1400 A/m2,electric quantity 17 F/mol,temperature 40 ℃ and flowrate of electrolyte 015 m/s?The yield was over 88%.
