Disperse Orange 73 Use and Manufacturing

Methods of Manufacturing

Taking N-cyanoethyl-N-hydroxyethylaniline and p-nitroaniline as raw materials, firstly N-cyanoethyl-N-hydroxyethylaniline and benzoyl chloride are benzoylated to obtain intermediate (I) . Then the p-nitroaniline is diazotized and coupled with (I) to obtain the product. After filtering, grinding and drying, the finished product is obtained.

Uses

Disperse Orange R-SF is suitable for the dyeing of polyester and polyester-cotton and polyester-acetate fibers and the printing of its fabrics. It has bright colors, medium dyeing depth and good transferability, and excellent fastness. It is still one of the main components of black dye 2B-SE.
