ELECTROCHEMICAL METHOD FOR MANUFACTURING METHYL ETHYL KETONE

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/m . 本发明提供了一种通过使用由铅制成的高氢过电压阴极在水性介质中电还原乙偶姻而制备甲基乙基酮的方法，该方法包括以下步骤：a)通过将乙偶姻与水性介质以及在此类介质中可溶的支持电解质混合而形成溶液，和b)通过使用直流电源以500至5000A/m的电流密度在阳极和所述阴极之间施加电压，在电化学反应器中连续或不连续地电解所述溶液。
