4-(4-Aminophenyl)benzenamine double nitriding, then respectively and 7-Hydroxynaphthalene-1,3-disulfonic acid and phenol coupling, garnish with 4-Methylbenzene-1-sulfonyl chloride make phenol hydroxyl esterification.
Properties and Applications
yellow light red. Red powder. In the water solubility have certain (red), in ethanol in a certain solubility (orange). Strong sulfuric acid in purple, it will be diluted brown is orange. Its water solution and strong hydrochloric acid generation wine red precipitate; Add sodium hydroxide solution is orange brown. In dyeing copper and iron ion colored light slightly dark, encounter chromium ion changed little. Mainly used for wool, silk and polyamide fiber fabric dyeing. And in the polyamide, silk, wool fabric printing directly, can also be used for leather, plastic and synthetic resin casein color.
