Abstract

4653. Ransford, R. B., [Cassella & Co., L.]. Feb. 24. Dyes, artificial; p-oxyphenyl-p-oxyxylylamine and its derivatives.-Violet dyes containing sulphur and possessed of excellent affinity and very great intensity are produced from p-oxyphenyl-p-oxyxylylamine or the indophenol from which it is obtained by reduction, or derivatives of these compounds, by heating them with alkaline polysulphides. An example is given in which a mixture of the indophenol corresponding to p-oxyphenyl-p-oxyxylylamine with a solution of sodium sulphide and sulphur is concentrated until it boils at about 120‹ C., and then heated for 12-16 hours at the reflux condenser. The melt is diluted with water and the dye-stuff is filtered off and dried. The process may also be carried out in other ways, e.g., an alcoholic solution of the materials may be heated in a closed vessel. The indophenols employed are produced by oxidizing at 0‹ C. a mixture of a solution of p-xylenol (CH3:CH3:OH # 1:4:5), or other xylenol, in caustic soda lye and p-amidophenol hydrochlorate, or p-amidophenol sulphonic acid, by means of sodium hypochlorite solution.
