Disperse Violet 33 Usage And Synthesis

Preparation

2-Cyano-4-nitroaniline diazo, and 3-Methyl-N,N-bis(2-acetoxyethyl)benzenamine?coupling .

Flammability and Explosibility

Not classified

Properties and Applications

red light purple. Sauce red powder. Dye bath of iron, copper ions in light of the impact is not big. Dye bath appropriate pH value for 5 ~ 7, after dyeing and printing to alkali resistance. The color of the dyes for yellow red jade, levelness medium, coverage is better, and is suitable for dyeing of high temperature and high pressure, the dyeing speed faster. Can also be used to melt method dyeing, hot melt appropriate temperature of 210 ~ 220 ℃, the carrier is not suitable for dyeing method. In the two vinegar on fine performance is, in three vinegar fine performance on compatible, the dyeing properties of the fiber in bad. Can two vinegar in fiber, three vinegar polyester fabric fiber or directly on printing. Available for ferrie sulfate-potassium thiosulfate white agent, for printing the discharge of the white color. And C.I. Disperse Violet 40 chemical structure is the same.
