Abstract
1-Acylamino-8-halogenanthraquinone is converted into the 1-acylamino-4 : 8-dihalogenanthraquinone which is then caused to react with 2 molecular proportions of a 1-aminoanthraquinone and the product finally treated with a condensing agent to form a vat dyestuff. According to an example, 1-benzoylamino-8-chloranthraquinone is converted with sulphuryl chloride into 1 - benzoylamino - 4 : 8 - dichlor - anthraquinone, the product is condensed with 1-aminoanthraquinone, and the violet-brown product obtained is condensed in presence of aluminium chloride and pyridine, followed by vatting. The product dyes cotton brown tints, which are redder after treatment of the dye with hypochlorite to purify it. 1-Carbethoxy and 1 - benzoylamino - 8 - chloranthraquinones chlorinated and brominated respectively in the 4-positions, are also specified for reaction with 1-aminoanthraquinone and its 4- and 5-benzoylamino and 4 : 3-acridone derivatives and others, followed by condensations with aluminium chloride to give similar brown cotton dyes. An example of the process of vat-dyeing the material with the product of the above example, whereby a brown-red tint is obtained, is also given.
