SIRIUS ORANGE G Usage And Synthesis
Preparation
1-Naphthol-3,7-disulfonic acid diazo, and 2-Amino-4-methylanisole coupling, and then make the light gasification.
Properties and Applications
bright orange. Tan powder. Soluble in water, slightly soluble in alcohol. The strong sulfuric acid dyes for dark blue, diluted into blue light green. The dye solution for yellow orange, join strong hydrochloric acid into a dark blue light green, precipitation; With strong sodium hydroxide solution for yellow orange still, accompanied by precipitation. Water-soluble is very good, hard to not sensitive. In dyeing copper and iron ion colored light basic unchanged. Used for cotton, viscose and their blended fabric and silk dyeing and not used in printing, also used for paper and leather dyeing. Neutral and alkaline white good to very good. But with disperse dyestuff with bath dyeing polyester/cotton blended fabric.
