Abstract: The invention relates to a process for obtaining at least one aromatic amine from a liquid mixture comprising water and the at least one aromatic amine by extracting with at least one nitroaromatic in an extraction column (1) to form an essentially water-comprising raffinate stream and an extract stream comprising the at least one nitroaromatic and the aromatic amine. The extraction column (1) is divided by a dividing wall (3) into two regions (5, 7), and, in the case of an amount of liquid for separation which is less than a minimum cross sectional loading of the entire extraction column (1), the liquid mixture to be separated is fed only to one of the regions (5, 7) of the extraction column (1) divided by the dividing wall (3). The invention further relates to a process for preparing an aromatic amine and to an apparatus for separating a liquid mixture comprising water and at least one aromatic amine by extracting with at least one nitroaromatic, comprising an extraction column (1).

Abstract: A process for hydrogenating a hydrogenatable organic compound in a reactor including a fixed catalyst bed. The fixed catalyst bed includes monolithic shaped catalyst bodies having pores and/or channels. The catalyst bodies include at least one element selected from Ni, Fe, Co, Cu, Cr, Pt, Ag, Au, Pd, Mn, Re, Ru, Rh and Ir. The CO content in the gas phase within the reactor during hydrogenation is within a range from 0.1 to 10,000 ppm by volume. In any section in the normal plane to flow direction through the fixed catalyst bed, at least 90% of the pores and channels have an area of not more than 3 mm2.
