Disperse Blue 183 Use and Manufacturing

Methods of Manufacturing

Method 1: Using p-nitroaniline and m-acetamido-N, N-diethylaniline as raw materials, firstly p-nitroaniline is brominated, diazotized, and then with m-acetamido-N, N-diethyl The aniline is coupled and then cyanated to obtain the product. After filtering, grinding and drying, the finished product is obtained. . Method 2: Using 2-cyano-4-nitroaniline and m-acetamido-N, N-diethylaniline as raw materials, firstly bromide and diazotize 2-cyano-4-nitroaniline, and then Coupling with m-acetamido-N, N-diethylaniline to obtain the product. After filtering, grinding and drying, the finished product is obtained.

Uses

Disperse Blue SE-2R is used for dyeing and printing of polyester fabrics. It is the main dye for dyeing dark colors. It can be combined with disperse yellow SE-FL and disperse ruby SE-GFL. It can also be used to dye blue. It can also be used to dye triacetate fiber, the dyeing rate is not high, not suitable for dyeing other fibers.
