DIRECT YELLOW 50 Chemical Properties,Usage,Production

Preparation

3-Aminonaphthalene-1,5-disulfonic acid diazo, and a coupling m-Toluidine, then the light gasification.

Properties and Applications

red light yellow. Soluble in water for golden brown, solubility of 60 g/L (60 ℃), 80 g/L (97 ℃), slightly soluble in ethanol, insoluble in other organic solvents. The strong sulfuric acid for quality in red, dilute for green light blue after blue precipitation; In nitric acid solution for purple. The dye solution to join strong hydrochloric acid has the purple precipitation; Add thick sodium hydroxide solution with gold orange precipitation. Cellulose fiber of dyeing, in 80 ℃ maximum when affinity, for the neutral, weak acid dye bath dyeing. Hard to not sensitive. In dyeing copper and iron ion colored light basic unchanged. Mainly used for cotton, viscose, which silk dyeing and printing, and can directly printing, also can to discharge printing color. Can and disperse dyestuffs high temperature polyester/cotton with bath dyeing blended fabric. May also used for the dyeing nylon, leather, paper and electrochemical aluminum color.
