Direct Blue 151 Usage And Synthesis
Preparation3,3′-Dimethoxylbenzidine double nitriding, first and 4-Hydroxynaphthalene-1-sulfonic acid conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling.
Properties and Applicationsred light blue. Blue-black powder. Soluble in water for blue purple or purple solution, and adequate soluble in ethanol for red light purple. The strong sulfuric acid in blue or green for Tracy blu-ray, diluted for purple. The dye solution to join strong hydrochloric acid for purple, have precipitation; Add thick red or purple sodium hydroxide solution for red wine. Cellulose fiber of dyeing, dye devoured rate is very good, temperature in 100 ℃, the largest affinity, discharge the gender is good. When dyeing with copper sulphate treatment can improve a resistance fastness, with?formaldehyde treatment can improve washing fastness. Mainly used?for cotton, linen, rayon and other cellulose fibers, rayon / brocade fabric dyeing, leather and paper pulp can also be used for coloring.
