UsesA useful stain with color index of 18050.
Preparationaniline diazo, and 4-Acetamido-5-hydroxynaphthalene-2,7-disulfonic acid coupling.
DefinitionChEBI: An organic sodium salt that is the disodium salt of 5-acetamido-4-hydroxy-3-(phenyldiazenyl)naphthalene-2,7-disulfonic acid.
Properties and Applicationscolourful red blue light. Red powder. Soluble in water solution for big red, slightly soluble in ethanol and soluble fiber element, insoluble in other organic solvents. Meet strong sulfuric acid is blue light red, it will be diluted in a yellow after red; Meet nitric acid solution is orange turn orange; Meet strong hydrochloric acid generation red precipitation, dilute it dissolve. The aqueous solution of dyes and strong hydrochloric acid is product red; Add sodium hydroxide is orange brown. Copper ions in dyeing and dark blue colour and lustre to take; Iron ion in color with blue and light. Good levelness. Mainly used in strong acid medium in the wool dyeing and the piece dyed wool.
