Abstract

PURPOSE: To produce the captioned ester at high current efficiency by electrolytically reducing oxalic acid diester with the oxalic acid in an alcohol solvent as a supporting electrolyte in cathode chamber in the electrolytic cell using a cationic exchange mambrane as a diaphragm.
CONSTITUTION: In the electrolytic cell using a cationic exchange membrane as a diaphragm, the solution comprising dissolving oxalic acid diester being a reaction substrate and oxalic acid being a supporting electrolyte in an alcohol is used for catholyte. The solvent or supporting electrolyte constituting anolyte are not particularly limited, but usually an aqueous sulfuric acid solution or an alcohol solution using catholyte containing sulfuric acid is used. According to this method, glyoxylic acid ester is formed at high current efficiency through electrolytic reduction of oxalic acid diester without undergoing glyoxylic acid ester alcholate and with virtually no admission of the by-production of glyoxylic acid as in conventional methods.
