Acid Red 151 Use and Manufacturing

Methods of Manufacturing

Using 4-aminoazophenyl-4'-sulfonic acid and 2-naphthol as raw materials, first diazotize the former and couple with the latter to obtain the product.

Uses

Weak acid red BL is suitable for dyeing nylon, silk, wool and wool fabrics. Leveling is good. It is also used for direct printing of silk and wool fabrics, with good whiteness. When used in the same bath dyeing of wool and various fibers, acetate fibers and cellulose fibers are stained. It is also used to color leather, paper and polyamide plastics.

Manufacturing Info：

Benzenesulfonic acid, 4-[2-[4-[2-(2-hydroxy-1-naphthalenyl)diazenyl]phenyl]diazenyl]-, sodium salt (1:1): ACTIVE
