Direct Green 6 Use and Manufacturing

Methods of Manufacturing

Using 4, 4'-diaminoazobenzene, H acid, phenol, and p-aminophenol as raw materials, 4, 4'-diaminoazobenzene is firstly double-nitrided, coupled with H acid, and then with phenol for the second time Coupling, diazotizing p-aminophenol at the same time, and finally coupling with the above-mentioned trisazo compound to obtain the product. After salting out, filtering and drying, the finished product is obtained.

Uses

Used for dyeing cotton, hemp and other fibers

Material
