C.I. Reactive Blue 13 Use and Manufacturing

Methods of Manufacturing

Using H acid, cyanuric chloride, amino C acid, aniline, copper sulfate, hydrogen peroxide, etc. as raw materials, first condense the H acid with cyanuric chloride, then diazotize the amino C acid, couple with the aforementioned condensation products, and then Copper sulfate is used for complexation in an oxidizing medium, and finally a second condensation with aniline is carried out, and the finished product is obtained by salting out, filtering and drying.

Uses

Used for dyeing cotton or viscose fiber

Material
