Abstract
315,910. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). April 20, 1928. Sulphuretted dyestuffs are prepared by heating binaphthylenedioxide with sulphur and/or a sulphur halide. A solvent or diluent may be present. According to examples, binaphthylene dioxide is heated with sulphur, sulphur monochloride, sulphur monochloride and nitrobenzene and with sulphur monochloride and sulphur. In another example, binaphthylenedioxide is first heated with sulphur dichloride, then sulphur is added and the reaction completed.
