Abstract
The present invention relates to a hydrogenation process for the production of aromatic halogen-amino compounds by means of catalytic hydrogenation on noble metal catalysts of corresponding aromatic halonitro compounds, characterised in that a rhodium, ruthenium, iridium, platinum or palladium catalyst which is modified with an inorganic or organic phosphorus compound with a degree of oxidation of less than V, is used, in the presence of a vanadium compound.
