Abstract
An anthraquinone dyestuff is obtained by reacting a 2-p-halogenobenzoylaminoanthraquinone with 4-aminoanthraquinone-2 : 1-(N)-benzacridone, e.g. in nitrobenzene or naphthalene solution preferably in the presence of an acid binding agent such as sodium carbonate and a copper-containing substance such as cuprous chloride. In examples, 4-aminoanthraquinone-2 : 1-benzacridone is reacted with (1) 2-p-bromobenzoylaminoanthraquinone, (2) 2-p-chlorobenzoylaminoanthraquinone. 2-p-Halogenobenzoylaminoanthraquinones are obtained by reacting 2-aminoanthraquinone with p-halobenzoyl chloride. The halogen atom may be chlorene or bromine. 4-Aminoanthraquinone-2 : 1-(N)-benzacridone is obtained as described in Specification 587,006.
