Proposed is a method for producing isocyanates by means of phosgenation of the respective amines in a fluidised bed reactor (R), characterised in that a gas flow (1) containing the phosgene is used as a swirl gas and keeps an inert solid suspended, and that a liquid flow (2) containing the amine is dosed into the fluidised bed, wherein the amine partially or completely vaporises, and reacts with the phosgene, while maintaining a reaction gas mixture containing the respective isocyanate, which is drawn out of the fluidised bed reactor. |
