Preparation7-Aminonaphthalene-1-sulfonic acid diazo, and 2-Ethoxynaphthalen-1-amine?coupling, product to diazo, and 4,5Dihydroxynaphthalene-1-sulfonic acid coupling.
Properties and Applicationsblue light green. Soluble in water for blue light green, also soluble in solution, fiber, slightly soluble in alcohol, insoluble in other organic solvents. In the light of sulfuric acid is palm black, dilute for shallow blue light after green; In nitric acid for olive, and brown to yellow. The dye solution to join strong hydrochloric acid for blue light green, precipitation;?Adding concentrated sodium hydroxide solution for the gray light blue, there is precipitation.
