摘要
Process for the reduction of halogenated hydrocarbons and for obtaining their derivatives in an electrolytic cell which includes at least one cathode, at least one anode and a solution. A hydrogen- permeable membrane is arranged in the at least one anode such that the at least one anode constitutes a hydrogen-diffusion anode, and hydrogen or a hydrogen-containing gas is supplied to the hydrogen-permeable membrane. An electrolytic cell for the reduction of halogenated hydrocarbons includes at least one high overpotential cathode containing lead, cadmium, graphite, copper and/or tin, at least one hydrogen- diffusion anode containing palladium and a solution. Another process for the reduction of halogenated hydrocarbons and production of derivatives thereof entails dissolving the halogenated hydrocarbons in a solution, contacting the halogenated hydrocarbons in the solution with a high overpotential cathode and a hydrogen-diffusion anode including a hydrogen-permeable membrane, supplying hydrogen or a hydrogen-containing gas to the anode such that H.sub.2 diffuses through the anode, oxidizing such H.sub.2 at the anode to form H.sup.+ ions and electrons and electrochemically reducing the halogenated hydrocarbons at the cathode.
