Disclosed is a method of reducing the cathodic voltage of an electrolytic cell while electrolytically producing alcohols, aldehydes, acids, and ketones from peroxy bond-containing organic compounds such as peracids, peroxides, hydroperoxides, and derivatives thereof. According to the disclosed method, the peroxy bond-containing organic compound is fed to the catholyte compartment of an electrolytic cell and an aqueous chloride solution, e.g., sodium chloride or hydrochloric acid, is fed to the anolyte chamber of the cell while passing an electrical current from an anode of the cell to a cathode of the cell. Chlorine is recovered as the anodic product of the cell while the reaction products of the peroxy bond-containing organic compound are recovered as cathodic products. Also disclosed is a method of electrolyzing aqueous chloride solutions, e.g., sodium chloride solutions, and hydrochloric acid solutions at a reduced cell voltage. In addition to the steps of feeding the chloride solution to an electrolytic cell, passing an electrical current from an anode of the cell to the cathode of the cell, evolving chlorine on the anode of the cell, and recovering the chlorine gas from the anolyte chamber of the cell, the disclosed method also includes feeding an oxidant to the catholyte chamber of the cell and recovering cathodic reaction products of the oxidant, in addition to water and alkali metal hydroxides, from the catholyte chamber. Disclosed oxidants include organic compounds containing peroxy bonds such as peracids, peroxides, hydroperoxides, and their derivatives where the cathodic reaction products of the oxidant are alcohol, ketone, aldehyde, or acid corresponding to the peroxy-containing organic oxidant.
