  • Patent number: 9120036
    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).
