Preparation2-Chloro-4-nitrobenzenamine diazo, and N,N-bis(2-hydroxyethyl)-3-methylbenzenamine?coupling between.
Properties and ApplicationsBlu-ray is red. Purplish red powder. Soluble in ethanol and soluble fiber element for blu-ray red, soluble in acetone, slightly soluble in benzene and carbon tetrachloride. The strong sulfuric acid as dark blue light in red, after diluted colourful red precipitate; In 10% of sulfuric acid to red; In 10% of sodium hydroxide solution for brown. In dyeing copper and iron ion to the colored light no effect. Dyeing appropriate pH value for 4 ~ 10, after dyeing and printing can be a resistance, but not resistant to restore: the dye for red sauce, mainly for the spell navy and black. Levelness general. Suitable for high temperature high pressure and dyeing of carrier, hot melt temperature of 190 ~ 200 ℃. In three vinegar on fiber can dye shallow. Dark, at two vinegar only on fiber dyed light color, not suitable for dyeing nylon, polyester fabric can be directly on printing, and can make the impression of the discharge printing. The chemical structure and C.I. Disperse Red 5 the same.
