Abstract

6546. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. March 28. Dinitrochlordi-p-hydroxydiphenylm-phenylenediamine is produced by condensing the molecular proportion of 3 : 5-dinitro-1 : 2 : 4-trichlorbenzene, which melts at 103‹À5 C., with two molecular proportions of p-amidophenol in presence of sodium acetate, or other agent which will bind hydrochloric acid. Dyes, artificial.-A new black dye, which yields on unmordanted cotton greener shades than the dye obtained as described in Specification No. 20,232, A.D. 1899, from dinitrodi-p-hydroxydiphenyl - m - phenylenediamine, is produced by heating the foregoing dinitrochlordi-p-hydroxydiphenyl-m-phenylenediamine with sodium sulphide and sulphur to 140‹ C., and then at 160‹ to 180‹ C. until the mass becomes dry. The product may be used directly for dyeing.
