Preparation
2-(1,3,3-Trimethylindolin-2-yl)acetaldehyde And 2-Methyl-2H-indazolein the presence of phosphorus oxychloride of condensation, and then quaternized..
Flammability and Explosibility
Not classified
Properties and Applications
colourful 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.
