Abstract

The reaction of 1-amino-2-phenoxy- or 1-amino-2-methoxy-4-hydroxyanthraquinone with the appropriate primary alcohols in the presence of polyethylene glycols which have a molecular weight of above 150 leads to 1-amino-2-alkoxy-4-hydroxyanthraquinones which carry a linear or branched alkyl in the alkoxy groups and in which the alkyl can additionally be further substituted. The process makes possible short reaction times and virtually complete reactions with those alcohols which react only incompletely or only very slowly under the conditions of the prior art. The process products are red to pink dyestuffs for synthetic fibres.
