配对电解合成乙醛酸的研究

以乙醛酸为模型产物，对配对电解合成技术进行了研究。草酸和乙二醛分别在阴、阳两极室内进行配对电解，使两极室中电解产物均为乙醛酸，产率各为２８．２％和２１．５％。若采用大面积的多极式电极，则产率可大幅提高。配对电解可使电耗降低一半，是有应用前景的合成技术。

Electrosynthesis of Glyoxylic Acid by Paired Electrolysis

Paired electrosynthesis using glyoxylic acid as a model product has been studied in this paper. Glyoxylic acid was produced at both of anode and cathode which were separated by a cation-exchange membrane. The catholyte was an oxalic acid solution while the anolyte was a solution of containing glyoxal and hydrochloric acid. The productivities were 28.2% and 21.5% respectively. With this electrosynthesis technique the electricity consumption may be reduced by fifty percent. The paired electrolysis technology has a brilliant future.
