The production method of Reactive Blue 194:

Reactive Blue 194 uses p-aminobenzene sulfonic acid, H acid, 2,4-diaminobenzene sulfonic acid, cyanuric chloride, and meta-Chemicalbook (2-sulfate ethyl sulfone) aniline as raw materials. Diaminobenzene sulfonic acid is condensed with cyanuric chloride for the first time, then diazotized, and coupled with H acid for the first time, then p-aminobenzenesulfonic acid is diazotized, and coupled with H acid for the second time, Finally, m-(2-sulfate ethylsulfone) aniline was added for the second condensation to obtain Reactive Blue 194 product. After salting out, filtering, and drying, the finished product Reactive Blue 194 is obtained.
