Abstract
Process for the dehalogenation of halogen-containing aromatic amines takes place by the action of hydrogen in the presence of a controlled-action hydrogenation catalyst, at a temperature of between 280.degree. and 420.degree. C., the active phase of the catalyst containing, in addition to the main catalyst metal, a minor amount of an auxiliary hydrogen catalyst consisting of a second metal which is different from the first.
