Direct Black 22 Use and Manufacturing

Methods of Manufacturing

Using 4, 4'-diaminodiphenylamine-2-sulfonic acid, gamma acid, and m-phenylenediamine as raw materials, firstly, 4, 4'-diaminodiphenylamine-2-sulfonic acid is double-nitrided and coupled with gamma acid , And then double nitridation of the coupled product, and then coupled with m-phenylenediamine for the second time to obtain the product. After salting out, filtering, drying and crushing, the finished product is obtained.

Uses
