| abstract | A compound of the formula <FORM:0659021/IV (c)/1> in which one X and one Y each represent hydrogen and the other X and the other Y each represent a halogen atom or hydrogen, is acylated with a reactive derivative of an aromatic monocarboxylic acid. The products dye or print cotton, artificial silk, or regenerated cellulose yellow shades. In examples, 5-amino-isophthaloyl di-(11-anthraquinonylamide) is acylated by heating in nitrobenzene with (1) m- or pmethylsulphonyl benzoyl chloride; (2) benzoyl chloride; (3) p-N-dimethylsulphonamido benzoyl chloride; (4) diphenyl sulphone-4-carboxylic acid chloride; (5) b -naphthoyl chloride; (6) m - methylmercapto benzoyl chloride. Also in examples, 5-amino-isophthaloyl di-(61-chlor-11-anthraquinonyl amide) is acylated with (7) m-methyl sulphonyl benzoyl chloride; (8) benzoyl chloride; (9) b -naphthoyl chloride; (10) diphenyl 4-carboxylic acid chloride. Anthraquinone carboxylic acids may also be used as acylating agents. A dyeing example is also given. The compounds of the above formula are obtained by reacting 5-nitroisophthalic acid chloride with the appropriate 1-amino-anthraquinone and reducing the nitro group. |
