Abstract
The work examines a possible process for the electrolytic reduction of oxalic acid to glyoxylic acid. The reaction is investigated in filter press type cells varying from small bench scale to pilot plant size and it is shown that the product can be produced with current efficiencies better than 70% and chemical yields better than 90%. It is demonstrated that the cell product containing 8–10 wt% of glyoxylic acid can be concentrated to the commercial specification of a 50 wt% aqueous solution.
