Abstract

Selon l'invention, on fait réagir la 1-nitro-anthmquinone avec des monoalkylamines en presence d'un éther et/ou d'un hydrocarbure. Les 1-alkylamino-anthraquinones sont obtenues directement selon l'invention dans un état de pureté suffisant pour la transformation en colorants.According to the invention, 1-nitro-anthmquinone is reacted with monoalkylamines in the presence of an ether and / or a hydrocarbon. The 1-alkylamino-anthraquinones are obtained directly according to the invention in a state of purity sufficient for conversion into dyes.
