The invention relates to a method for producing amines by hydrogenating nitro compounds and is characterized in that the hydrogenation is carried out in a vertical reactor whose diameter is larger than its length. The reactor comprises a jet nozzle which is arranged in the upper area of the reactor and which is directed downwards. The educts and the reaction mixture are delivered via said jet nozzle. The reactor also comprises an outlet situated in any position of the reactor via which the reaction mixture in an outer circuit is delivered once again to the jet nozzle by means of a conveying organ, and the reactor has a flow reverse situated in the lower area of the reactor. |
