Direct Blue 71 Chemical Properties,Usage,Production

  • Chemical Properties black powder
  • Uses Direct blue 71 (CAS# 4399-55-7) is an organic triazo dye and a water-soluble pollutant. The decolourization of aqueous solutions of direct blue 71 has been achieved using a variety of methods, such as the use of Au-Nx-TiO2 nanospheres to achieve its photocatalytic degradation. Dyes and metabolites.
  • Preparation 3-Aminonaphthalene-1,5-disulfonic acid diazo, and Naphthalen-1-amine first coupling, its product to diazo, and 8-Aminonaphthalene-2-sulfonic acid second coupling, again diazo, in alkaline conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid third coupling.
  • Properties and Applications dark blue. Blue gray powder. Soluble in water for blue, solubility of 10 g/L (60 ℃), 20 g/L (97 ℃), slightly soluble in soluble fiber element, soluble in ethanol, insoluble in other organic solvents. The strong sulfuric acid for blue to to black, red after diluted purple precipitation. Dye with strong hydrochloric acid solution for blue precipitation; Add thick sodium hydroxide solution for red light purple, have precipitation. Cellulose fiber of dyeing, dye devoured the gender is good, the temperature in the 80-100 ℃, affinity is the largest. Discharge sex is very good. In dye bath of copper ions in tiny change color (4 ~ 5 level), meet iron ion colored light basically unchanged (level 5). SDC classification for a class B. Cotton neutral white was a category 4, viscose neutral white for 4 ~ 5 level, cotton and viscose alkaline white are 5 levels. Widely used in viscose fiber dyeing, also used in viscose/PVA blends, cotton, and the carpet of dyeing and printing. Also used in leather, paper, soap, cheese, protein and formaldehyde resin color.
