Abstract
5018. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. March 7. Halogen derivatives of diamidoanthraquinones.- Chlorinated and brominated derivatives of diamidoanthraquinones are produced by any of the usual chlorinating or brominating processes. For example, dry chlorine gas is passed through a mixture of 1 : 5-diamidoanthraquinone and chloroform, or glacial acetic acid, until unchanged diamidoanthraquinone is no longer present. The residue is filtered off and dried, and when recrystallized from nitrobenzene or aniline it yields yellowish-red needles with a metallic lustre. A brominated compound is obtained by exposing a layer of 1 : 8-diamidoanthraquinone in a chamber to the fumes of bromine from an open vessel therein, then washing the product with dilute sodium-bisulphite solution, and drying it. When recrystallized from pyridine or nitrobenzene, the bromo derivative yields brownish-red crystals with a metallic lustre. Dyes, artificial, which contain halogen and sulphur and dye unmordanted wool in acid baths violet to blue shades, are produced by acting with fuming sulphuric acid containing about 40 per cent. of free SO3, at 110‹-120‹ C. for 1 to 2 hours, upon the above chlorinated and brominated derivatives of diamidoanthraquinone. The product is cooled, poured into water, boiled, and filtered, and the resulting paste is ready for dyeing. If boric acid is present as well as fuming sulphuric acid. products are obtained which yield fast greenish-blue to reddish-blue shades on chromiummordanted wool. The processes of chlorinating or brominating and sulphonating may be carried out in one operation, with or without the addition of boric acid. For example, bromine is stirred into a solution of 1 : 8-diamidoantbraquinone, boric acid, and fuming sulphuric acid, while the temperature is maintained below 50‹ C., and the mixture is then heated to 180‹ C. for 3 hours. The dye-stuff produced is subsequently isolated as above described.
