| Uses | Acid Blue 120 (CAS# 3529-01-9) is an organic azo dye used for colouring wool/acrylic blended fabrics. |
| Preparation | 3-Aminobenzenesulfonic acid diazo, and Naphthalen-1-amine coupling, its product to diazo, and 8-(P-toluidino)naphthalene-1-sulfonic acid coupling. |
| Properties and Applications | red light navy blue. Deep purple uniform powder, soluble in water is purple, soluble in ethanol is deep blue. In a dark of sulfuric acid, a green light blue after diluted. The aqueous solution of this product with strong hydrochloric acid formation of dark precipitation; Add thick sodium hydroxide solution is Red sauce. In dyeing copper and iron son, colour and lustre is a little dark, encounter chromium ion have little influence. Discharge sex differences. Mainly used for wool, polyamide fiber and fabric dyeing of silk. But with the direct dyes dyed wool/stick with blended fabric. Can also be used for leather, paper and biological shading.
