1'-ヒドロキシ-4-[[4-[(1-ヒドロキシ-4-ソジオスルホ-2-ナフタレニル)アゾ]-7-ソジオスルホ-1-ナフタレニル]アゾ]-6'-フェニルアミノ[1,2'-アゾビスナフタレン]-3',7-ジスルホン酸二ナトリウム 化学特性,用途語,生産方法
製造方法
8-Acetamido-5-aminonaphthalene-2-sulfonic acid diazo, and 5-Aminonaphthalene-2-sulfonic acid?coupling, again diazo, coupled with the 4-Hydroxynaphthalene-1-sulfonic acid, and then hydrolysis usions amino, again diazo, and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid coupling.
Properties and Applications
blue. Soluble in water as dark blue, not soluble in alcohol. The strong sulfuric acid in dark green light for blue, blue for diluted. The dye solution to join strong hydrochloric acid color unchanged, but have precipitation; Add thick sodium hydroxide solution same color, have precipitation.
