    摘要： The invention relates to a method for producing isocyanates by reacting the corresponding amines with phosgene in the gas phase, optionally in the presence of at least one inert medium. Said phosgene is guided into a reactor (21) through a first inlet and the amine is guided through a second inlet of an ejector (1). The first inlet and the second inlet join in a mixing area (17) in which the phosgene and the amine are mixed to form a reaction mixture. A diffuser (19) that is joined to the mixing area (17) increases the pressure and the temperature of the reaction mixture consisting of phosgene and amine.

    摘要： The invention relates to a method for producing isocyanates by reacting amines with phosgene in the gaseous phase in a reaction zone, whereby in order to terminate the reaction, the reaction mixture is guided through a zone, into which a liquid is injected. The invention is characterised in that the reaction mixture is guided between the reaction zone and the zone into which the liquid is injected, through a zone with a reduced flow cross-section.

    摘要： 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.
