Direct Green 26 Usage And Synthesis
Preparation2,4,6-Trichloro-1,3,5-triazine in turn and (1) 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid, (2) 4-Nitrobenzenamine diazo, and 2-Hydroxybenzoic acid coupling, and then to restore the azo dyes, (3) aniline for condensation, and for this coupling components (A), 4-Amino-5-hydroxynaphthalene-2,7-disulfonic aciddiazo, and 2-Amino-4-methylanisole coupling, its product to diazo, and the generation of coupling components (A) coupled.
Flammability and ExplosibilityNonflammable
Properties and Applicationsblue light green. Soluble in water for the green, solubility of 20 g/L (80 ~ 85 ℃), insoluble in organic solvents. The strong sulfuric acid for yellow green, dark blue after diluted precipitation, with zinc and ammonia reduction for green light yellow. In dyeing of copper (colored light yellow, iron ion in a dark colored. Is very sensitive to that fights. Can be used for cotton, viscose, silk and PVA/rayon blended fabric dyeing and printing directly, also used in leather, paper and regenerated celluloee fiber film color.
