Hazard Information | Back Directory | [Uses]
Acid green 20 is a green dye that can be decolorized by ultrasonic irradiation. | [Preparation]
4-Nitrobenzenamine diazo, in acid conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, and its product under alkaline conditions and then with the coupling diazotized aniline, and reducing the nitro group with sodiumn. | [Properties and Applications]
dark blue light green green light to dark. Dark green light to black powder. Soluble in water and soluble fiber element, slightly soluble in alcohol, insoluble in other organic solvents. Dyes in 10% of sodium hydroxide solution for purple solution; The strong sulfuric acid for blue-ray green, diluted into blue, precipitation; In nitric acid solution for brown. The water solution is dark blue light green, add thick sodium hydroxide solution to purple. This product is suitable for the wool, silk, wool blended fabric, polyamide fiber of dyeing and printing, also suitable for leather and paper color.
