Abstract
1 - Amino - 6,7 - dichloranthraquinone is acylated with a p-halogenbenzoyl chloride or a p-phenylsulphonyl benzoyl chloride. The p-phenyl radical may be substituted. The products dye or print cotton, linen, artificial silk or regenerated cellulose yellow shades. In examples, 1-amino-6,7-dichloranthraquinone is acylated with p-chloro-, bromo-, iodo-, or fluoro-benzoyl chloride, and with diphenylsulphone-4-carboxylic acid chloride and its 41-methoxy derivative. 1 - Amino - 6,7 - dichloranthraquinone is obtained by nitration of 2,3-dichloranthraquinone and reduction.
