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.
L'invention concerne un procédé de synthèse électrochimique directe de phosgène en phase gazeuse, selon lequel une cellule électrochimique (1) est utilisée avec une membrane conduisant les protons (4). Du gaz HC1 sec et du gaz CO sec sont acheminés jusqu'à l'anode (2) de la cellule électrochimique (1), comme éduits. Les radicaux chlore formés lors de l'oxydation anodique du gaz HC1 réagissent ensuite avec le gaz CO pour former directement du phosgène. Les protons produits migrent simultanément à travers la membrane (4), jusqu'à la cathode (3) où ils sont réduits en hydrogène ou en eau, en présence d'oxygène.
