Abstract

11,717. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. May 22. Dyes, artificial.-The yellow product described in Specification No. 3239, A.D. 1901, is transformed, by heating with halogen acids, into blue dye-staffs containing halogen. These dye-stuffs may be used to form vats which dye unmordanted cotton blue shades, fast to the action of chlorine. The dye obtained from hydrochloric acid forms a paste which can be used directly for dyeing. It is soluble in nitrobenzene, aniline, and quinoline, forming blue solutions, and crystallizes from quinoline in blue needles. The dye obtained from hydrobromic acid is also soluble in sulphuric acid, forming a brown solution. The dyes are more easily soluble than the blue dyes described in the above-mentioned Specification.
