Introduction and application of CAS：8011-86-7| Acid Brown 75
Acid brown B is suitable for dyeing wool, nylon and wool blended fabrics, and has excellent dyeing fastness. Also widely used for coloring leather. The production method uses H acid, p-nitroaniline, 2-amino-4,6-dinitrophenol and resorcinol as raw materials. First, H acid is diazotized and coupled with resorcinol. Then 2-amino-4,6-dinitrophenol is diazotized and coupled with the first coupling product for the second time. Finally, the p-nitro group is Aniline is diazotized and subjected to the third coupling with the second coupling product to obtain the product. After salting out, filtering, drying and crushing, the finished product is obtained. . .
