Abstract

332,203. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). April 15, 1929. Anthraquinone derivative s.-Acid wool dyestuffs are obtained by condensing a 1-amino-4- halogenanthraquinone-2-sulphonic acid with an aminonitrile of the benzene series, advantageously in the presence of an acid-binding medium and a copper catalyst. In an example, 1-amino-4- bromoanthraquinone-2-sulphonic acid is condensed with m-aminabenzonitrile in presence of soda and cuprous chloride to give a reddish-blue dye. The 1-amino-3-cyan-4-(and 5-)-methylbenzenes may be condensed in a similar manner to give greener dyes. Specifications 10378/14 and 7861/15 are referred to.
