Abstract
Process for the preparation of acid anthraquinone dyes, characterized in that an anthraquinone compound of the general formula i ** (see formula) ** In which Hal means a halogen atom up to the atomic number 35, and X means hydrogen or the sulfonic acid group, It is reacted in the presence of an acid-binding agent and a copper catalyst at a temperature of 50 -100ºC and at a ph value of at least 5, with an amine of the general formula ii ** (see formula) ** In which B means the -oh group or the group (see formula) wherein r represents hydrogen or a lower alkyl group and the phenylene ring a may still be further substituted, to form an anthraquinone dye of the general formula iii ** (see formula) ** In which X and b have the significance indicated under formulas i and ii.
