Abstract

273,656. I. G. Farbenindustrie Akt.- Ges. July 1, 1926, [Convention date]. Benzanthrone derivatives. - The 2-benzanthronyl - 1 - aminoanthraquinones obtainable bv cendensing 2 - halogenbenzanthrones with 1- aminoanthraquinones are treated with acid condensing agents; the products dye vegetable fibre from the vat in orange-red, brown, and violetbrown shades. According to examples (1) 2-benzanthronyl-1-aminoanthraquinone (obtained from 2-chlorbenzanthrone and 1-aminoanthraquinone in presence of copper salts and an acid-fixing agent) is heated with concentrated sulphuric acid and boric acid or with a mixture of aluminium and sodium chlorides; (2) the condensation products from 2 : 6-dichlorbenzanthrone (1 mol.) and 1-aminoanthraquinone (2 mols.), from 2-chlorbenzanthrone and 1-amino-6-chloranthraquinone and from 2 : 6-dichlorbenzanthrone (1 mol.) and l-amino-4-methoxyanthraquinone (1 mol.) are heated with concentrated sulphuric acid; (3) the condensation product from 2-chlorbenzanthrone (1 mol.) and 1 : 6-diaminoanthraquinone (1 mol.) is heated with aluminium and sodium chlorides.
