What is Direct Blue 82?
Preparation
2-Aminobenzene-1,4-disulfonic acid diazo, and 8-Aminonaphthalene-2-sulfonic acid coupling, again diazo, and Naphthalen-1-amine coupling, again diazo, in alkaline conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling.
Properties and Applications
blue. For blue is soluble in water, soluble in ethanol, insoluble in other organic solvents. The strong sulfuric acid for violet black, diluted for purple. The dye water solution is blue, with strong hydrochloric acid have dark violet blue precipitation; Add thick sodium hydroxide solution have red light purple precipitation.
