- 26 - ABSTRACT Process for the dehalogenation of halogen- containing amino- or nitro-aromatic compounds, which leads to the preferential production of amino-aromatic derivatives carrying a smaller number of halogen atoms, at least one of which is substituted in the meta-position relative to the amino group, in the vapour phase and at a temperature between 280° and 420°C by the action of hydrogen in the presence of a controlled-action hydrogenation catalyst comprising copper or silver deposited on an alumina-based support, characterised in that the support used is modified, at least on the surface, by the incorporation of a metal in the form of a salt or an oxide, this incorporation consisting in treating the support with the said metal salt or metal oxide and then carrying out a calcination at a temperature ranging from about 500° to 1000°C.
