synthetische
2-Aminobenzenesulfonic acid diazo, and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling, and then again with 2,4,6-Trichloro-1,3,5-triazine?condensation.
Properties and Applications
bright orange. Yellow light red powder. Solubility 100 g/L (50 ℃). In the 20 to 40 ℃ can in alkaline medium of the fibers in dyeing, levelness is better. Alkaline hydrolysis, not resistant to acid hydrolysis. The strong sulfuric acid for red, diluted into red orange; In nitric acid to orange, no change after diluted. Water solution is orange, add 1 Moore sodium hydroxide to a bit deep red, continue to add insurance powder and warm, into light yellow, join a boric acid sodium can’t return to them. Apply to cotton, wool, silk, nylon and viscose fiber yarn and fabric dyeing, suitable for dyeing or disseminated, high affinity. Viscose fabric can also be used for direct, resist printing..
