4065. Farbwerke vorm. Meister, Lucius, & Br³ning. March 5, 1910, [Convention date]. 4-Aminoanthraquinone-1:2-thioxanthone and derivatives thereof, which are vat dyes, are obtained by treating 4-aminoanthraquinone-1- thiosalicylic and, or derivatives thereof substituted in the benzene nucleus, with dehydrating-agents, such as sulphuric acid, chlorsulphonic acid, or zinc chloride. 4-Aminoanthraquinone-1-thiosalicylic acid and derivatives thereof are obtained by condensing 1-chlor-4-aminoanthraquinone with thiosalicylic acid or its derivatives. Reference has been directed by the Comptroller to Specification 30,480/09.
