ABSTRACT:
Disclosed is an improved method for the electrochemical production of pinacols from organic carbonyl compounds at high current efficiency in an acid medium in a cell having a hydraulically impermeable cation-exchange membrane. Aqueous organic carbonyl compound and sulfuric acid are introduced to the cathode compartment of the cell along with copper ions in controlled concentrations. After passing an electrolyzing current between the anode and cathode of the cell the pinacol is recovered from the cathode compartment effluent.
