Abstract: The invention provides a process for preparing amines by catalytic hydrogenation of nitroaromatics and subsequent removal of the catalysts from the reaction mixture, which contains at least one aromatic amine and water, which comprises carrying out the removal of the catalysts by means of membrane filtration, which is carried out at a pressure on the suspension side of from 5 to 50 bar, a pressure difference between the suspension side and the permeate side of at least 0.3 bar and a flux rate on the suspension side of from 1 to 6 m/s.

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.

Abstract: Production of a supported nickel catalyst involves co-precipitating nickel and at least one other metal (M), selected from silicon, zirconium, hafnium, alkaline earth metals, yttrium, lanthanum and cerium, and optionally a Group 5-11 metal dopant, from a solution containing the corresponding metal salts onto a particulate titania (TiO2) support, and drying, calcining, reducing and optionally passivating the product. An Independent claim is included for a process in which the above catalyst is used.
