Active brilliant blue K-GR method for the preparation of intermediates

The invention provides a preparation method of a reactive brilliant blue K-GR intermediate. The preparation method comprises following steps: carrying out a condensation reaction between bromamine acid and 2,4-diaminobenzene sulfonic acid or sodium 2,4-diaminobenzene sulfonate with a catalyst system containing a cuprous complex for catalyzing the reaction to obtain the reactive brilliant blue K-GR intermediate (sodium 1-amino-4-((4-amino-3-sulfonylphenyl)amino)-anthraquinone-2-sulfonate). By means of the preparation method of the reactive brilliant blue K-GR intermediate, usage amounts of cuprous chloride and copper powder can be effectively reduced, thereby reducing the content of heavy metals in a dye product, reducing the content of heavy metals in waste water and reducing environmental pollution and production cost. In addition, the preparation method can avoid generation of a hydrolyzed by-product (a purple by-product) of the bromamine acid, can greatly reduce the generation of a debromination by-product, can significantly reduce the generation of a double-condensation substance, can increase yields of the condensation reaction and the dye product and can reduce discharge amount of waste water containing acids and being high in chroma.

MECHANISM OF THE ULLMANN CONDENSATION

It has been found that the condensation rate of 1-amino-4-bromoanthraquinone-2-sulphonic acid (I) with 1,3-diaminobenzene-4-sulphonic acid (II)giving 1-amino-4-(3'-amino-4'-sulphoanilino)anthraquinone-2-sulphonic acid (III) in media of NaHCO3 - CO2 and NaHCO3 - Na2CO3 with catalysis by CuI obeys the kinetic relation v = k, being controlled by the kinetic relation v = k2 in media of NaH2PO4 - Na2HPO4 buffers.The suggested reaction mechanism presumes formation of a bifunctional catalyst CuCO3 or Cu2PO4(1-) which splits off the proton and bromide anion from the reaction intermediate in the rate-limiting step.
