C.I. Basic Brown 1 Use and Manufacturing

Methods of Manufacturing

Using m-phenylenediamine as the main raw material, firstly, 1 mol of m-phenylenediamine was double-nitridated with NaNO2, HCl at low temperature to obtain m-phenylenediamine double nitrogen salt, and then coupled with 2 mol of m-phenylenediamine, and then salted out, filtered, The finished product is dried.

Uses

Alkaline brown can be used for dyeing cotton, wool, silk, viscose fiber and acrylic fiber, but the fastness is slightly worse, and the fastness to sunlight is all 1-2. It can also be used for the dyeing of leather, paper, bamboo and wood and for the manufacture of lakes.
