2,7-Naphthalenedisulfonic acid, 4-amino-6-[[4'-[(8-amino-1-hydroxy-5-sulfo-2-naphthalenyl)azo]-3,3'-dimethyl[1,1'-biphenyl]-4-yl]azo]-5-hydroxy-3-[(2-methyl-5-nitrophenyl)azo]-, trisodium salt 化学特性,用途語,生産方法
製造方法
2-Methyl-5-nitrobenzenamine diazo, in acid conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, 3,3′-Dimethylbenzidine double nitriding, first in alkaline conditions and formation of accidentally coupled nitrogen compounds, again in alkaline conditions and 4-Amino-5-hydroxynaphthalene-1-sulfonic acid coupling.
Properties and Applications
dark green light blue. Soluble in water for a blue-black, and adequate soluble in ethanol is light blue. The strong sulfuric acid for blue-black, diluted for dark purple. The dye solution to join hydrochloric acid have navy precipitation; Add thick sodium hydroxide solution for the navy.
