Reactive Black 5 Use and Manufacturing

Methods of Manufacturing

Using p-(2-sulfate ethyl sulfone) aniline and H acid as raw materials, first diazotize the former, and then couple with H acid for the first time in a strong acid medium (at the amino position ortho to the amino group). Coupling with H acid for the second time under natural conditions (ortho to the hydroxyl group). After salting out, filtering and drying, the finished product is obtained.

Uses

Used for dyeing and printing cotton, viscose and other fibers

Dyes
