REACTIVE GREEN 19 Use and Manufacturing

Methods of Manufacturing

Using H acid, p-nitroaniline o-sulfonic acid, cyanuric chloride, and p-aminobenzenesulfonic acid as raw materials, firstly diazotize p-nitroaniline o-sulfonic acid, couple with H acid, and reduce it with sodium sulfide. Cyanuric chloride undergoes the first condensation, and then with p-aminobenzenesulfonic acid for the second condensation to obtain the product. After salting out, filtering and drying, the finished product is obtained.

Uses

For dyeing cotton and linen fabrics

Reactive green 19 can be used for dyeing and printing of cotton fiber.
