3-Amino-4-hydroxybenzenesulfonamide diazo, and 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one coupling, and then the chrome complexation with 2-Hydroxybenzoic acid?into 1:2 chromium complex dyes. | [Flammability and Explosibility]
Nonflammable | [Properties and Applications]
red light orange. Orange or yellow brown powder, its water solution to gel state. The strong sulfuric acid for yellow, diluted the same colour and lustre, precipitation appear; No change in strong hydrochloric acid, diluted solution into orange, and the precipitation; In nitric acid solution for golden, diluted into orange red solution; In the thick partly dissolved sodium hydroxide solution for orange red, diluted unchanged. Water solution is orange. Used for wool, silk, tussah, polyamide, PVA, PVA/cotton, wool/stick blended fabric dyeing and printing. This product can and alkalinity rose essence spell color red color oil made ball pen, can also be used in leather dyeing. |
