Manufacturing Methods : 3-Aminobenzenesulfonic acid diazo, and Naphthalen-1-amine coupling, its product to diazo, and 8-(Phenylamino)naphthalen-1-ol coupling.
Properties and Applications: red light navy blue. Green light black powder. Purple soluble in water, soluble in ethanol is violet blue, also soluble in soluble fiber element, slightly soluble in acetone, insoluble in other organic solvents. Meet sulfuric acid as dark green light blue, it will be diluted in deep green light blue to grey purple; Nitric acid in a orange brown solution. Its water solution and strong hydrochloric acid is purple; Add thick sodium hydroxide solution is purplish red color. In dyeing copper and iron ion, the former slightly darker, the latter slightly becomes shallow. Discharge the gender is poorer. Used for wool, polyamide fiber and fabric dyeing of silk, also can with the direct dyes with bath dyed wool/stick blended fabric, can also be used in leather, paper and biological shading.
