Abstract: In a process for the preparation of 1-amino-2-phenoxy-4-hydroxyanthraquinone by reacting 1-amino-2-halogeno-4-hydroxyanthraquinone with a phenol in an alkaline aqueous medium at an elevated temperature, the improvement that 1-amino-2-chloro-4-hydroxyanthraquinone is reacted in aqueous suspension, at a pH of from 9 to 13 and at from 120 DEG to 150 DEG C., with the phenol in the presence of (a) ammonium salts N(+)(R)4A(-), wherein one or more R's are linear or branched C4-C20-alkyl or C7-C10-phenylalkyl and the remaining R or R's may also be phenyl or N(+)(R)3 may be pyridinium, and A(-) is one equivalent of an anion, of (b) ethylene oxide/propylene oxide block copolymers or of (c) oxyethylation products of alkylphenols, of alkenylamines, of alkylamines or of alkanols. A very pure product is obtained, in high yield.
