Preparation | 4-(4-Aminophenyl)benzenamine double nitriding, first in acid conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, Naphthalen-1-amine again diazo, in alkaline conditions and formation of accidentally coupled nitrogen compounds, and then coupled with phenol. | Properties and Applications | dark green. Soluble in water for the green, and adequate soluble in ethanol is green. The strong sulfuric acid is a deep in the navy, diluted for light gray. The dye solution to join strong hydrochloric acid for a dark grey light green, precipitation, add thick sodium hydroxide solution have olive green precipitation.
