Abstract

13,057. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. June 5. Dinitro-1 : 2<1>-dianthraquinonylamine is produced by treating 1 : 2<1>-dianthraquinonylamine, described in Specification No. 19,199, A.D. 1905, with nitric acid in presence of nitrobenzene. Dyes, artificial.- A dye, dyeing cotton blue shades, is obtained when the dinitrodianthraquinonylamine described above is fused with alkali sulphide. Preferably, a little caustic alkali is added to the sulphide.
