Abstract

279,003. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). May 12, 1926. Anthraquinonecarbazoles are produced by treating condensation products from halogenphenanthrenequinones and 1-amino-benzoylaminoanthraquinones with acid condensing agents such as aluminium chloride, chlorsulphonic acid, and sulphuric acid. The products dye cotton in yellow-brown and red-brown shades from the vat. According to examples (1) the condensation product from 1 mol. dibromphenanthrenequinone and 2 mols. 1-amino-5-benzoylaminoanthraquinone is treated at room temperature with sulphuric acid of 66‹ BÚ and the product worked up by pouring into water containing sodium nitrite; (2) the condensation product from 1 mol. dibromphenanthrenequinone and 2 mols. 1-amino-4-benzoyiaminoanthraquinone is treated with chlorsulphonic acid at 40-45‹ C. and the product similarly worked up. Specifications 9888/09 and 278,771 are referred to.
