Reactive Blue 49 Use and Manufacturing

Methods of Manufacturing

With bromamine acid, 2, 4, 6-trimethyl-3, 5-diaminobenzenesulfonic acid, m-aminobenzenesulfonic acid and cyanuric chloride as raw materials. Firstly, bromamic acid is condensed with 2, 4, 6-trimethyl-3, 5-diaminobenzenesulfonic acid, then with cyanuric chloride, and finally with m-aminobenzenesulfonic acid to obtain the product. After salting out, filtering and drying, the finished product is obtained.

Uses

Reactive Brilliant Blue P-3R is used in the dyeing of cotton and viscose fibers, and the printing of its fabrics. It has excellent dyeing fastness and is an important blue dye.
