Abstract
The present disclosure concerns a process and a system for the electrochemical reduction of oxalic acid to glyoxylic acid. The process involves withdrawing a portion of oxalic acid-depleted catholyte from the process and contacting it with a quantity of solid oxalic acid to provide a concentrated oxalic acid solution which is re-entered into the process.
