Abstract
Indirect oxidation of maleic acid by hydrogen peroxide electrochemically generated in situ from oxygen in the gas-diffusion electrode in 1 M Na2SO4 has been studied. The oxidation of substrate in divided cell with cation-exchange membrane is shown to proceed to malic acid, and in undivided cell destructive oxidation occurs to CO2 and H2O.
