Abstract

3 : 31 - Dichloro - N - dimethyl - 1 : 2 : 21 : 11-anthraquinoneazine (3 : 31 - dichloro - N-dimethylindanthrone) is manufactured by subjecting 1 : 3-dichloro- or 1-bromo-3-chloro-2-methylaminoanthraquinone to condensation with a copper catalyst, e.g. copper powder or a copper salt, e.g. copper acetate, in the presence of an acid binding agent, e.g. sodium carbonate or sodium or potassium acetate, and a high boiling solvent, e.g. o-dichlorobenzene, nitrobenzene or naphthalene. The product dyes cotton blue shades from a red-brown hydrosulphite vat by the cold dyeing method. Specification 484,679 is referred to.
