Preparation3,3′-Dimethylbenzidine double nitriding, first coupling with 3-Aminonaphthalene-2,7-disulfonic acid, again with phenolcoupling, and then under the pressure of monomer (VCM) and heat, make phenol hydroxyl into b oxygen radicals.
Properties and Applicationsred light orange. Soluble in water for orange to brown orange, soluble in ethanol for gold orange. In the strong sulfuric acid as dark blue, diluted red for ash brown, with black precipitation. The dye solution to join strong hydrochloric acid for olive brown, have precipitation; Add thick sodium hydroxide solution for palm light orange, precipitation. Used for cellulose fiber, silk, polyamide, wool dyeing, cellulose, silk and wool printing, also can be used for leather and paper color. Exhaust dyeing and good levelness.
