Abstract: The invention relates to a process for distillatively preparing TDA from a reactant stream comprising TDA, high boilers and low boilers in a dividing wall column in which a dividing wall is disposed in the longitudinal direction of the column to form an upper combined column region ( 2 ), a lower combined column region ( 3 ), a feed section ( 4 ) having a rectifying section ( 5 ) and stripping section ( 6 ), and also a withdrawal section ( 7 ) having a rectifying section ( 9 ) and stripping section ( 8 ), which comprises the following steps: a. feeding the reactant stream ( 13 ) into the feed section ( 4 ) of the dividing wall column ( 1 ); b. drawing off a low boiler fraction via the top of the column ( 11 ); c. drawing off TDA via a side draw ( 14 ) in the withdrawal section ( 7 ) of the dividing wall column ( 1 ); d. drawing off a low boiler fraction via the bottom of the column ( 12 ).

Abstract: Preparation of aromatic amines, preferably tolylenediamine, comprises catalytic hydrogenation of nitro compounds, preferably dinitrotoluene in the presence of hydrogenation catalyst with an active component mixture containing platinum, nickel and an additional metal on a substrate. Independent claims are included for: (1) catalyst for the preparation of aromatic amines, comprising hydrogenation catalyst with an active component mixture containing platinum, nickel and an additional metal on a substrate; and (2) the preparation of hydrogenation catalyst, comprising mixing the substrate with an aqueous solutions of at least platinum salt, nickel salt and copper salt, cobalt, iron, zinc, manganese or chromium; evaporating the water; adding water-soluble basic compound; and reducing the produced catalyst with hydrogen.

Abstract: Method for aminating hydrocarbon involves physically removing hydrogen from the reaction mixture. An independent claim is included for a procedure for the production of aniline, comprising providing benzene and ammonia separately or together in a reaction mixture, which leads to cycle that exhibits a membrane reactor with catalyst and hydrogen permeable membrane, where the reaction mixture takes place at 10-150 bar, and removing the aniline from the cycle.

Abstract: The invention relates to a process for the partial or complete separation of a mixture comprising hydrogen chloride and phosgene, possibly solvents and possibly low boilers and inerts as are typically obtained in the preparation of isocyanates by reaction of amines with phosgene, which comprises firstly carrying out a partial or complete condensation of phosgene, then a distillation or stripping step in a column to remove the hydrogen chloride from the bottom product phosgene and subsequently a scrub of the top product hydrogen chloride by means of the process solvent to absorb the phosgene in the process solvent. An after-purification by means of adsorption on activated carbon or by another suitable method can subsequently be carried out to remove solvent residues.

Abstract: The invention relates to a process for preparing isocyanates by reaction of amines with phosgene in the presence of inert organic solvents in a reactor and subsequent work-up of the reaction mixture leaving the reactor, wherein the solvent is separated off in a two-stage or multistage, preferably two-stage, distillation process in which the solvent is separated off at a pressure of 0.1-15 bar in a first apparatus and at 1-900 mbar in a second apparatus or further apparatuses, with the heat of condensation of the solvent vapor from the first apparatus being used for partial or complete vaporization of solvent in the second apparatus.
