| titleOfInvention | One-pot synthesis of reactive deep black |
| abstract | One-pot synthesis to prepare an aqueous mixture of Reactive Black, comprising the following steps from a) to f): a) dissolving 2 - [(4-aminophenyl) sulfonyl] ethanesulfonic acid (parabase vinyl sulfone ester) in water; b) diazotizing the dissolved parabase vinyl sulfone ester using excess nitrous acid or using excess nitrite and an acid, resulting in a remaining diazonium salt and nitrous acid; c) quenching the remaining nitrous acid with sulfamic acid; d) Coupling the diazonium salt from step c) with 4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid (H-acid) until the reaction is complete, obtaining as a result Reactive Black 5 (RB 5) and salt of remaining diazonium, e) coupling the remaining diazonium salt with 7-acetamido-4-hydroxy-2-naphthalenesulfonic acid (acetyl-j) until completion of the reaction, resulting in Reactive Orange 78 (RO 78); and f) obtaining the aqueous reactive black mixture in which: - steps a) to e) are performed without intermediate purification and at least steps d) and e) are performed under high shear mixing conditions, and - the combined concentration of RB 5 and RO 78 at the end of step e) is greater than 0.1 mol / L. |
