Abstract: Processes for separating carbon monoxide from a hydrogen chloride-containing gas, which comprise reacting the carbon monoxide with chlorine to form phosgene and then optionally separating the phosgene from the hydrogen chloride-containing gas. The hydrogen chloride-containing gas that is used preferably derives from a phosgenation or isocyanate forming reaction.

Abstract: Processes for the production of organic isocyanates, comprising the production of phosgene by reaction of CO with Cl2, the reaction of the phosgene with organic amines to form the organic isocyanates, and the separation of the organic isocyanates, which is characterised in that the carbon monoxide is removed from the HCl-containing waste gas from the isocyanate synthesis by reaction with chlorine to form phosgene. The phosgene can be separated off and can optionally be fed back into an isocyanate synthesis The HCl-containing, CO-depleted gas is preferably subjected to HCl oxidation (Deacon). A closed chlorine cycle can be used in the isocyanate synthesis.
