Abstract

276,408. Carpmael, W., (I.G. Farbenindustrie Akt.-Ges.). May 13, 1926. Hydroarylaminoanthraquinones are produced by introducing hydroaromatic amine residues into anthraquinones by the customary methods. The sulphonic acids of the products dye wool in clear blue shades which are faster to light than those given by alkylaminoanthraquinone sulphonic acids. According to examples, (1) 1-amino-4- bromanthraquinone-2-sulphonic acid is condensed with hexahydroaniline or hexahydro-o-toluidine in presence of sodium carbonate, copper sulphate, and alcohol or pyridine; (2) leuco-1: 4-dioxyanthraquinone is condensed with o-aminocyclohexanol and the 1: 4-di-(o-oxyhexahydroanilido)- anthraquinone converted into its disulphuric ester by means of sulphuric acid; (3) 1-methoxy-4- p-toluidoanthraquinone is condensed with hexahydroaniline in presence of pyridine under pressure and the product sulphonated in the toluidine residue.
