Abstract (en)
[origin: WO2011018443A2] The invention relates to a method for producing diisocyanates by gas-phase phosgenation, starting from an educt flow comprising the corresponding diamines and a phosgene, the educt flows each being separately converted to the gas phase and preheated to the reaction temperature of the gas-phase phosgenation, characterized in that waste heat from a plant for producing chlorine by heterogeneous catalyzed oxidation of hydrogen chloride using the Deacon method is used to this end.
