    Abstract

    The electrocatalytic hydrogenation (ECH) of a model alpha-functionalized carboxylic acid, benzoyl formic acid was carried out using constant potential electrolysis using different types of electrodes. The concentrations of the final products, hexahydro mandelic acid, cyclohexyl 1,2-ethanediol and mandelic acid were determined under different conditions of step potential, substrate concentration, pH and temperature. Results of the study of product concentrations from both Pt./diamond and Pt/Ru/diamond electrodes are presented as a function of the various conditions. Both the electrodes show highest concentrations of the electrohydrogenation products at a potential of around -0.4V (vs. Ag/AgCl), substrate concentration of 10ppm and pH 2. The optimum temperature for ECH was found to be 90°C on Pt/diamond and 25°C on Pt/Ru/diamond.
