摘要： 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 of 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 of at least Cl2 is produced from HCl and/or a metal chloride on the anode side, wherein phosgene is produced from the gaseous products.
