摘　　要：在对称双阳极室电解槽中,以草酸水溶液为阴极液,乙二醛与盐酸为阳极液,电解后在阴阳极两室内可同时得到乙醛酸.研究表明:时空产率、电流效率等技术指标较单阳极室成对法高.Glyoxylic acid is produced by electroreduction in a well designed double - anode cell reactor. The cathodic and anodic electrolytes are oxalic acid and glyexal solution with hydrochloric acid separated by an ion - exchange membrane. The current efficiency and yield of glyoxylic acid are studied under different current densities. The results indicate that the average time - space yield of glyoxylic acid in the double - anode cell is higher than that in the single - anode cell.
