Uses
C.I. Acid red 106 is an acid red dye that can be adsorbed and removed by bentone clay.
Preparation
(a) aniline diazo, and 8-(4-Methylphenylsulfonamido)-1-naphthol-3,6-disulfonic acid coupled; (b) anilinediazo, and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acidin alkaline conditions coupled, then and 4-Methylbenzene-1-sulfonyl chloride reacts amide sulfonylurea medications.
Properties and Applications
red. Soluble in water is blue light red, soluble in ethanol red, slightly soluble in acetone. Meet strong sulfuric acid in deep red, a muddy after diluted (red light purple); Nitric acid solution in orange. Used for wool, silk and polyamide fiber fabric dyeing and printing. Can also be used to electrochemical aluminum, paper, leather shading, and can be used to manufacture color pigment sediment.
