Abstract (en)
[origin: DE19543678A1] The invention relates to a process for direct electrochemical gaseous phase phosgene synthesis, during which an electrochemical cell (1) with a proton-conducting membrane (4) is used. Dry HC1 gas and dry CO gas are fed as educts to the anode (2) of the electrochemical cell (1). The chlorine radicals obtained during anodic oxidation of HC1 gas subsequently react with the CO gas directly to form phosgene, while the protons formed simultaneously migrate through the membrane (4) to the cathode (3) where they are reduced to form hydrogen or, in the presence of oxygen, to form water.
