Abstract (en)
[origin: WO2008055904A1] The invention relates to a method for producing isocyanates by reacting amines with phosgene in the gas phase in at least one reaction zone, the reaction mixture being guided to at least one zone in which at least one liquid is injected to terminate the reaction. The invention is characterized by guiding the reaction mixture through a continuous quenching liquid curtain which completely fills the cross-section of the quenching zone.
