Abstract (en)
[origin: WO2020207874A1] 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.
