Preparation
2-Amino-3,5-dimethylbenzenesulfonic acid diazo, and 2-Amino-4-methylanisole coupling, its product to diazo, in alkaline conditions and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid coupling.
Properties and Applications
blue purple. Purple powder. For the red light purple is soluble in water, soluble in soluble fiber element, slightly soluble in ethanol and acetone, insoluble in other organic solvents. The strong sulfuric acid dyes in dark green for blue-ray, diluted into blue; In nitric acid for blue-ray in green, to dark brown. The dye solution to join strong hydrochloric acid into blue, precipitation; Add thick sodium hydroxide solution to purple, have precipitation. 60 ℃ the solubility of 15 when g/L, 97 ℃ the solubility of 25 g when/L, not sensitive to that fights. For blue light purple, dyeing encounter copper, iron ion colored light are a little red. For A class SDC classification. To dead cotton covered the gender is poorer, cotton and glue neutral white are 4 ~ 5 level, cotton white alkaline for 4 ~ 5 level, viscose alkaline white into four grades. Used for cotton, viscose, wool, silk and polyamide fiber dyeing and printing directly. Can also be used for leather, paper, water-based ink color.
