Abstract: Preparation of aromatic amines or aliphatic amino alcohols comprises hydrogenating nitro-aromatic compounds or nitro alcohols, respectively in the presence of a catalyst, separating the catalysts from fluid amine- or amino alcohols containing reaction mixture, in a reactor, and measuring the absorption of UV/visible-radiation by the reaction mixture to determine the concentration of nitro and nitroso compounds. An independent claim is included for a device for executing the preparation of aromatic amines or aliphatic amino alcohols.

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.
