Chemical PropertiesEasily soluble in water is greenish yellow. Dye powder in concentrated sulfuric acid is light orange, diluted greenish yellow. The color and luster of the dye remain unchanged when it meets copper ions, and the color and luster change slightly when it meets iron ions.
Preparation2-(1,3,3-Trimethylindolin-2-yl)acetaldehyde And 2-Methyl-2H-indazolein the presence of phosphorus oxychloride of condensation, and then quaternized..
Flammability and ExplosibilityNot classified
Properties and Applicationscolourful green light yellow. Bright yellow powder. Soluble in water. In the strong sulfuric acid of bright orange, diluted into green light yellow. In 120 ℃ high temperature dyeing, colored light unchanged. Copper ions in dyeing color shade unchanged, encounter iron ion colour and lustre micro have change. Compatibility value is 2.5, the f value is 0.29. Solubility of 40 g/L, effected by temperature is very small. Mainly used in acrylic dyeing, also can be in acrylic fiber directly on printing.
