Abstract
278,771. Carpmael, W., (I. G. Forbenindustrie Akt.-Ges.)- May 12, 1926. Anthraquinonecarbazoles are obtained by treat ing the condensation products from halogenphenanthrenequinones and 1-aminoanthraquinone with aluminium chloride. According to an example the condensation product from 1 mol. dibromphenanthrenequinone and 2 mols. 1-aminoanthraquinone (obtained according to Specification 9888/09), is heated with aluminium chloride and pyridine and the product purified by means of hypochlorite; it dyes cotton in reddish-brown shades from the vat.
