Abstract

Anthraquinone derivatives are prepared by splitting off sulphonic acid groups from anthraquinone sulphonic acids by slowly adding to an aqueous alkaline solution or suspension of an anthraquinone-b -sulphonic acid, or salt thereof, which is homonuclear substituted by hydroxy, amino, alkylamino or arylamino groups and which may be further substituted, a hydrosulphite in an amount of one molecular proportion on each sulphonic acid group to be split off. The aqueous alkali solution may contain alkali metal hydroxides, pyridine, piperidine or alkali metal or ammonium carbonates or bicarbonates. In examples, sulphonic acid groups are split off from (1) 1-amino-4-anilido-, 1 - amino - 4 - a - (or - b -) naphthylamino-, 1 - amino - 4 - hexahydroanilido -, 1 - amino - 4 - methyl (or - benzyl) amino - or 1 - amino - 4 - p - aminoacetanilido - anthraquinone - 2 - sulphonic acid; (2) 1 - hydroxy - 4 - aminoanthraquinone - 2 - sulphonic acid; (3) 1 : 5 - dihydroxy - 4 : 8 - diaminoanthraquinone - 2 : 6 - disulphonic acid (ether one or both sulphonic acid groups being removed); (4) diaminoanthrarufin monosulphonic acid; (5) quinizarin - 2 - sulphonic acid, (6) quinizarin - 2 - 6 - disulphonic acid (to obtain quinizarin - 6 - sulphonic acid, 1 - amino - 4 - anilido - 6 - chloranthraquinone - 2 - sulphonic acid, 1 - amino - 4 - hexahydroanilido - 8 - methoxyanthraquinone - 2 - sulphonic acid, 1 - amino - 4 - ethylamino - 5 - hydroxyanthraquinone - 2 - sulphonic acid and 1 - amino - 4 - toluidoanthraquinone - 2 : 8 - disulphonic acid. Specification 250,968, [Class 2 (iii)], is referred to.
