Abstract (en)

[origin: WO2019091653A1] The invention relates to a method for producing phosgene directly from the directly combined raw products, preferably only dried raw products, of a combined CO2 chloride electrolysis. A first gaseous product comprising CO is produced from CO2 on the cathode side in at least one electrolysis cell for a CO2 conversion into CO, and a second gaseous product comprising at least C12 is produced from HC1 and/or a metal chloride on the anode side, wherein phosgene is produced from said gaseous products.
