Abstract

4540. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. March 23. Dihalogenaminoarylaminoanthraquinones and sulphonic acids thereof are obtained by condensing trihalogen -a-aminoanthraqninones, containing at least one heteronuclear halogen in #-position, with aromatic amines or sulphonic acids thereof, and, if required, sulphonating the products. The sulphonated products are acid blue wool dyes; the unsulphonated products may be used in the manufacture of lakes. According to examples, dibrom -#-chlor-a-aminoanthraquinone is condensed with p-toluidine and the product is sulphonated; other dibrom -#-chloralpha-aminoanthraquinones, or tribrom-a-aminoanthraquinone, and aniline, are also specified as parent materials. Dibrom-#-chlor-a-aminoanthraquinones are obtained by nitrating, reducing, and brominating #-chloranthraquinone, or by brominating 1-amino-6- or -7-chloranthraquinone. Tribrom-alpha-aminoanthraquinone is obtained by treating 1-amino-6- or -7-bromanthraquinone with excess of bromine in hot nitrobenzene.
