Abstract

338,858. Chemische Fabrik vorm. Sandoz. Dec. 20, 1928, [Convention date]. Void Published under Sect. 91 of the Acts]. Arylaminoanthraquinone polysulphonic acids. -An arylaminoanthraquinone containing in the benzene ring to which is attached the arylamino group a halogen atom in a #-position, and in the other benzene residue a sulphonic acid group, is treated with sulphite in presence or not of phenol or similarly acting compound, whereby the #- halogen atom is replaced by a sulpho group. More than one sulpho atom may be present originally in the molecule, and the arylamino group may contain an acylamino group or other substitutent. In examples, the process of replacing the #-halogen atom by a sulpho-group in 1- amino-2-bromo-4-anilido-(and 4-p-aminoacetanilido-)-anthraquinone-5-sulphonic acid, 1-amino-2- bromo-4-anilidoanthraquinone-8-sulphonic acid, 1 - amino-2-bromo-4-p-toluidoanthraquinone-5-sulphonic acid, 1-amino-2- brom-4- [2"-sulpho-4"- methylanilido]-anthraquinone-5-sulphonic acid, 1- amino - 2-bromo-4-[3<1>-sulpho-4<1>-methylanilido-]- anthraquinone-5- or 8-sulphonic acid, is described. The products are water soluble and may be used for wool dyeing and printing; blue to greenishblue shades fast to light are obtained. Specification 288,878, [Class 81 (i), Disinfecting &c.], is referred to.
