Disperse Red 82 Use and Manufacturing

Methods of Manufacturing

Using 2-cyano-4-nitroaniline and N, N-diacetoxyethylaniline as raw materials, first diazotize 2-cyano-4-nitroaniline, and then diazotize it with N, N-diacetoxy Ethylaniline was coupled to obtain the product. After filtering, grinding and drying, the finished product is obtained.

Uses

Dispersed ruby SE-BBL is mainly used for dyeing and printing of polyester and polyester-cotton textiles. It is suitable for high temperature and high pressure dyeing and hot melt dyeing.
