Physical and Chemical Properties | Green band flash crystal. Soluble in water, easily soluble in ethanol, are blue-green. The dye was yellow in concentrated sulfuric acid and turned dark orange after dilution; Orange in concentrated nitric acid and orange-brown after dilution; The addition of sodium hydroxide to the aqueous solution produced a white precipitate with green light. Staining was performed at high temperature (120 ° C.), and the color light was unchanged. Dyeing on acrylic fibers the fastness to sunlight was 4-5. |
