| titleOfInvention | Improvements relating to Difficulty Water-Soluble Anthraquinon Dyestuff and their use |
| abstract | 1,160,621. Anthraquinone azo dyestuffs. J. R. GEIGY A.G. 24 Feb., 1967 [25 Feb., 1966], No. 8864/67. Heading C4P. The invention comprises azo-anthraquinone dyestuffs free from salt-forming water solubilizing groups and having the general formula wherein R 1 is H or C 1 -C 5 alkyl, X is a radical of an organic hydroxyl compound linked via the oxygen atom of the hydroxyl group, or a primary, secondary or tertiary amino group, Z is an optionally substituted carbocyclic-aromatic or heterocyclic aromatic radical and ring A may be further substituted. They are prepared by (1) condensing an anthraquinone having a 4- halogen, hydroxy, alkoxy or nitro group with an appropriate amino azo dye preferably in an excess of amine in a melt at 70-250‹ C. or in an organic solvent at 100-160‹ C. with an acidbinding agent and a catalyst, (2) condensing an anthraquinone-2-carboxylic acid halide with a compound HX preferably in an organic solvent, (3) reducing the corresponding 1- nitro compound, (4) condensing an anthraquinonel-halo, alkoxy, hydroxyl or nitro compound with an amino compound H 2 N-R 1 or (5) reacting an anthraquinone - 1 - nitro or 1 - NHR 1 - 2 - carboxylic acid ester with ammonia or a primary or secondary amine to obtain the 2-carboxylic acid amide and when Q is a nitro group simultaneously reducing this to the amino group. They are used to dye cellulose 2, 2¢ or tri-acetate, polyesters and nylon 6, 66 or 11 in green shades. |
