Acid Blue 277 Use and Manufacturing

Methods of Manufacturing

With bromamine acid and 3, 4-dimethylnitrobenzene as raw materials. First, 3, 4-dimethylnitrobenzene is chlorosulfonated (with chlorosulfonic acid), condensed with ethanolamine, and then the nitro group is reduced to obtain 3, 4-dimethyl-5-(hydroxyethylaminosulfonyl )aniline. Finally, the intermediate is condensed with bromamine acid to obtain the product. The finished product is obtained by salting out, filtering, drying and crushing.

Uses

Weak acid brilliant blue 4R is suitable for dyeing wool and nylon. The color is bright, with excellent level dyeing performance and strip cover dyeing performance, and excellent light fastness.
