Abstract: PROBLEM TO BE SOLVED: To provide an industrially practicable method for producing an amine by hydrogenation, consuming a small amount of a catalyst, greatly avoiding the occurrence of secondary reaction, capable of setting an excellent catalyst balance, excellently separating an inactive catalytic component. SOLUTION: This method comprises producing an amine by hydrogenating a compound containing at least one nitro group in the presence of a supported catalyst containing at least nickel as a catalytic active metal. The reduced and stabilized supported catalyst contains nickel microcrystal showing a two mode nickel microcrystal particle size distribution having maximum values at 30-80 Angstrom (300-800 nm) and 81-150 Angstrom (810-1,500 nm). The catalyst having 60-80 mass % nickel content, 0-20 mass % SiO2 content, 0-40 mass % ZrO2 content and 0-4 mass % HfO2 content in a reduced passivation state and at least 70% degree of reduction after further reduction for 1 hour at 100 deg.C is used.

Abstract: The invention relates to a method for hydrogenating liquid organic compounds, in particular for hydrogenating nitro compounds to obtain amines. Said method is characterised in that the hydrogen that is present in the reactor contains constituent parts of at least one gas that is inert during the hydrogenation reaction.

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: A catalyst comprising nickel on a TiO 2 support is obtainable by coprecipitation of nickel and at least one further metal selected from among Si, Zr, Hf, alkaline earth metals, Y, La and Ce, and optionally at least one dopant metal selected from groups 5 to 11 of the Periodic Table of the Elements, from a solution in which the corresponding metal salts are present onto a particulate TiO 2 support, subsequent drying, calcination and reduction and optionally passivation to give the nickel-containing catalyst. It is used, in particular, for the hydrogenation of nitroaromatic compounds.
