Acid yellow 25 Use and Manufacturing

Methods of Manufacturing

Using 4-amino-2-(anilinosulfonyl) methylbenzene and 3-methyl-1-p-sulfonic acid phenyl-5-pyrazolone as raw materials. First, the former is diazotized, and then coupled with the latter to obtain the product. After salting out, filtering, drying and crushing, the finished product is obtained.

Uses

Used for dyeing wool fabrics and printing and dyeing nylon
