| Abstract: | The process and devices of the electrolytic reduction of oxalic acid to glyoxylic acid have been improved. Under the optimized conditions, the process was stable with the pilot current efficiency 76.7%, chemical yield 92.5% and cell voltage 5.7 V. Based on the up results, the economic evaluation has been made and the further improvements were raised. |
