| abstract | 8438. Dreyfus, C., Tompkins, H. K., and Clayton Aniline Co. April 7. Halogenindigo dyes; halogenthioindigo dyes.- Dyes of the indigo or thioindigo classes are halogenated by treatment with chlorine or bromine in presence of antimony chlor-or brom-acetylide. Suitable diluents such as carbon tetrachloride, acetylene tetrachloride, or carbon bisulphide may also be present. The process can be applied to indigo, tolylindigo, #-naphthylindigo, mono- and di-chlor- and brom-indigo, indirubin, thioindigo, and dyes containing nitrogen and sulphur rings. The production of tri- and tetra-chlor-indigo, tribromindigo, chlorbromindigo, and tetrabromthioindigo is described in examples. The Provisional Specification also describes the production of monochlorindigo. Antimony chlor- and brom-acetylides are obtained by passing acetylene into antimony penta-chloride and bromide ; the antimony pentachloride is preferably employed mixed with a proportion of trichloride, and may be obtained by treating the metal with chlorine, or by chlorinating the trichloride. The chlor- and brom-acetylides are decomposed by chlorine and bromine with reformation of the pentachloride and pentabromide. |
