Abstract: The invention relates to a catalyst system suitable for hydrogenating aromatic nitro compounds (I) to form the corresponding aromatic amines (II), the catalyst system containing, as essential constituents: a component A selected from the group consisting of silicon carbide, corundum (alpha-Al2O3) and slightly porous to non-porous zirconium oxide (ZrO2); and a component B, containing B1—a carrier substance selected from the group consisting of silicon dioxide, gamma-, delta- or theta-aluminum oxide Al2O3, titanium dioxide, zirconium dioxide and graphite, B2—a metal or a plurality of metals selected from the group consisting of copper, nickel, palladium, platinum and cobalt, and optionally B3—an additional metal selected from the group consisting of at least one metal selected from main group I, main group II, main group IV and sub-groups II, V, VI and VIII of the periodic table of the elements, the proportion of component A being in the range of 5 to 60 wt %, in relation to the total weight of the catalyst system, and the aromatic nitro compounds (I) being those of the general formula R—(NO2)n, (I), and the aromatic amines (II) being those of the general formula R—(NH2)n, (II), and the moieties R and indices n in formulas (I) and (II) having the following meaning: R is a substituted or unsubstituted aromatic C6-C10 moiety and n is an integer from 1 to 5.

Abstract: A process for obtaining pure aniline contains catalytically hydrogenating nitrobenzene, to obtain a reaction mixture, separating the reaction mixture into a gas phase containing hydrogen and a liquid phase, liquid/liquid phase separating the liquid phase to obtain an aqueous phase and also crude aniline containing water as an organic phase, distillatively pre-purifying the crude aniline by removing the water via an overhead stream of a first distillation column to obtain a first bottom stream, feeding the first bottom stream as a feed stream to a pure column from which a pure aniline stream is taken off at the top and a second bottom stream containing high boilers is taken off, and passing the second bottom stream to incineration, by pumping the second bottom stream through heated pipelines and by adding methanol, ethanol, propanol, and/or acetone to the second bottom stream.
