Abstract
It is provided a process for the preparation of methyl ethyl ketone by electroreduction of acetoin in aqueous media using a high hydrogen overvoltage cathode made of lead, the process comprising the steps of a) forming a solution by mixing acetoin with an aqueous medium and a supporting electrolyte soluble in such a medium, and b) electrolyzing said solution continuously or discontinuously in an electrochemical reactor by applying a voltage between an anode and the cathode using a direct current power supply at a current density from 500 to 5000 A/m2.
