โฆ Synopsis
The electrolytic reduction of maleic and fumaric acids was studied with a rotating lead cathode. A current efficiency of 98 per cent with an assay yield of 95 per cent was obtained at a cathode current density of 20 A/dm 2. The choice of the cathode material is explained on the basis of the (~ potential. The difficulties due to a separate anode chamber were avoided by means of a leadlined copper rod covered with asbestos fibre. The results obtained with a rotating lead cathode are compared with those obtained using a stationary cathode under identical conditions of current density and temperature.
