Abstract: 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.

Abstract: The invention relates to a process for the preparation of amines by hydrogenation of nitro compounds, which comprises carrying out the hydrogenation in a vertical reactor whose length is greater than its diameter, having a downward-facing jet nozzle arranged in the upper region of the reactor through which the starting materials and the reaction mixture are fed in, and having an outlet at any desired point of the reactor, through which the reaction mixture is fed back to the jet nozzle in an external circuit by means of a conveying means, and having flow reversal in the lower region of the reactor.

Abstract: The production of amines (I) by hydrogenation of nitro compounds (II), carried out in a vertical reactor with length greater than its diameter. It has a spray at the top for introducing educts and reaction mixture and an outlet through which the reaction mixture is pumped into an external cycle. The circulation is reversed in the lower zone of the reactor.
