摘要： The invention relates to a method for the continuous production of polyisocyanates by reaction of organic amines with phosgene, characterised in that the reaction occurs in at least three stages, whereby the first stage is in a mixing unit, the second stage in at least one residence time unit and the third stage in at least one material separating apparatus and the pressure in each subsequent stage is lower than in the previous stage.

摘要： 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.

摘要： The invention relates to a method for treating distillation residues from the synthesis of toluene diisocyanate by reacting the distillation residues with water. The invention is characterized in that the TDI distillation residues are reacted with water in a continuos or semi-continuos method in a back-mixed reactor in the presence of hydrolyzates.
