    Abstract: A process for the manufacture of blue anthraquinonoid disperse dyes based on 1,5(1,8)-diamino-4,8(4,5)-dihydroxyanthraquinone, wherein 1,5(1,8)-dinitro-4,8(4,5)-dimethoxy-anthraquinone or mixtures of these compounds are reduced, in 20 to 45% strength by weight oleum, with sulfur at -10* to +50*C in the presence of boric acid, and the product of the reduction is brominated in sulfuric acid or 0 to 5% strength by weight oleum or in organic solvents until the product thus obtained contains 12 to 30% by weight of bromine. Dyes which give deep and, in particular, light-fast dyeings, above all on fibrous materials consisting of linear polyesters, are obtained.

    Abstract: The production of 3,6-dihalodiphenylalkanes by reaction of a diphenylalkane with a halogen and the novel 3,6dihalodiphenylalkanes themselves. The new compounds which can be prepared according to the process of the invention may be used as dispersing agents in dye/styrene mixtures and also as dyeing auxiliaries. They are also valuable starting materials for the production of dyes and pesticides.
