Title: Manufacture of vat dyestuffs of the anthraquinone series
IPC: C09B1/42
Filed: 1953-02-17
Abstract: The invention comprises dyes of the formula:  <FORM:0737016/IV (c)/1> in which at least one of the two halogen atoms is other than chlorine, and R is a benzene residue substituted para to the CO group or a naphthalene residue bound in 2-position to the CO group.  They are made by treating the corresponding 1 - amino - 6,7 - dihalogen-anthraquinones with acylating agents capable of introducing the residue of a p-substituted benzoic acid or a b -naphthoic acid. The products dye or print cotton, linen, artificial silk, or regenerated cellulose yellow shades, and may be converted to leuco-ester salts.  In examples, 4-chloro-, fluoro-, bromo-, or iodobenzoyl chloride is reacted with 1-amino-6,7-dibromoanthraquinone or with a mixture of 1-amino - 6 - chloro - 7 - bromo - anthraquinone and 1 - amino - 7 - chloro - 6 - bromo - anthraquinone, or mixtures of the corresponding 1-amino - chloro - iodo -, bromo - iodo, or chlorofluoro-anthraquinones, such mixtures being obtained by nitration and reduction from the corresponding 2,3 - dihalogen anthraquinones containing different halogens, (see Group IV (b)). Also in examples, diphenyl-4-carboxylic acid chloride is reacted with the mixture of isomeric amino-chloro-fluoro-anthraquinones referred to above, and other acid chlorides specified are those of naphthalene-2-carboxylic acid, 3-methoxynaphthalene - 2 - carboxylic acid, 4-methyl-, methoxy-, or methylsulphone-benzoic acid.  A dyeing example is given.ALSO:2,3-Dihalogen-anthraquinones having different halogen atoms are prepared by Sandmeyer reaction from 2 - amino - 3 - halogen - anthra-quinones, e.g. 2-chloro-3-bromo-anthraquinone, and 2-bromo-3-iodo-anthraquinone from 2-amino - 3 - bromo - anthraquinone, and 2 - chloro - 3 - iodo - antraquinone from 2 - amino-3-chloranthraquinone, and also by condensation of phthalic anhydride with dihalogen-benzenes, e.g. 2 - chloro - 3 - fluoro - anthraquinone from phthalic anhydride and o-chlorofluorobenzene.
