Abstract: In a process for the preparation of aromatic monoaldehydes by reacting monochlorinated methylaromatics with hexamethylenetetramine by a Sommelet reaction, the improvement that in place of pure chloromethylaromatics the chlorination mixtures produced by photochlorination of the methylaromatics are employed and are treated with hexamethylenetetramine without prior working up, after which the Sommelet reaction is allowed to take place.

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 DEG to +50 DEG 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.
