Abstract

311,283. I. G. Farbenindustrie Akt.- Ges. May 8, 1928, [Convention date]. Anthraquinone acridones.- Dianthraquinonylamines of the anthraquinoneacridone series are obtained by causing an aminoanthraquinone or a derivative or substitution product thereof to act on a polyhalogen anthraquinone-N-1 : 2-acridone, containing, in addition to halogen in the phenyl residue a halogen atom in the 4-position of the anthraquinone nucleus, in a high-boiling solvent in the presence of an acid-fixing agent and, as catalyst, copper or a salt thereof. The products are themselves vat dyes, and can be used as intermediates for the production or other vat dyes. In examples, trichloranthraquinacridone is heated in the presence of naphthalene, sodium acetate and cupric chloride with 1-benzoylamino- 4- or 5- aminoanthraquinone, and with 1-aminoanthraquinone; the products dye cotton from an alkaline hydrosulphite vat in grey shades. The product from 1-benzoylamino-5-aminoanthraquinone is identical with the condensation product from Bz-dichlor-4-aminoanthraquinoneacridone (made in accordance with Specification 17764/14, by the use of 3 : 5-dichlor-2-anthranilic acid) and 1-benzoylamino-5-chloranthraquinone Specification 305,082 also is referred to. The Specification as open to inspection under Sect. 91 (3) (a) is not limited to the use of copper or salts thereof as catalysts, and includes an additional example in which a. product dyeing cotton in corinth shades is obtained from trichloranthraquinoneacridone and 1-amino-4-methoxyanthroquinone. It also states that vat dyes of different shade and apparently of carbazole structure may be obtained by treating the products with condensing agents. This subject-matter does not appear in the Specification as accepted.
