Preparation

4-(4-Aminophenyl)benzenamine double nitriding, first with 2-Hydroxybenzoic acid coupling, again with 4-Aminonaphthalene-1-sulfonic acid matches. In some brands, Part of the 2-Hydroxybenzoic acid?can be 2-Hydroxy-3-methylbenzoic acid , and can be used other amino acid naphthalene replaced the 4-Aminonaphthalene-1-sulfonic acid.

Properties and Applications

red light orange. Moderate soluble in water (for orange brown) and ethanol (for palm light orange), slightly soluble in soluble fiber element and acetone, insoluble in other organic solvents. The strong sulfuric acid is a deep red in blue, diluted shallow sauce for red, precipitation. The dye solution to join strong hydrochloric acid for red sauce, precipitation; Add thick sodium hydroxide solution for orange, precipitation. Can be used for cotton dyeing and paper shading.
