Uses

Acid violet 7 (4321-69-1) is not only mainly used for wool, silk fabrics and dyeing of leather and paper, but also can be used for coloring soap, wood and cosmetics.

Production

Take P-aminoacetanilide and N-acetyl-H acid as raw materials, and have the diazotization of P-aminoacetanilide , and then has the coincidence of N-acetyl-H acid. After those,by salting out, filtration, drying, grinding to get the product .
