2-Naphthalenesulfonic acid, 7-[[4-chloro-6-[(3-sulfophenyl)amino]-1,3,5-triazin-2-yl]methylamino]-4-hydroxy-3-[2-(2-sulfophenyl)diazenyl]-, sodium salt (1:3) Use and Manufacturing

Methods of Manufacturing

Using aniline-2, 5-bissulfonic acid, J acid, cyanuric chloride and m-aminobenzenesulfonic acid as raw materials, first condense J acid and cyanuric chloride, and then reconstitute aniline-2, 5-bissulfonic acid. After nitriding, it is coupled with the above condensation product, and finally with m-aminobenzenesulfonic acid for the second condensation to obtain the product. After salting out, filtering and drying, the finished product is obtained. . . Condensation of 0.2625kmol cyanuric chloride and 0.25kmol J acid in a hydrochloric acid medium at a temperature of 0-5℃ to obtain (I). Take 0.25kmol aniline-2, 5-bissulfonic acid after diazotization and couple with (I) to remove insoluble impurities to obtain (II), and then condense with 0.275kmol m-aminobenzenesulfonic acid at a temperature of 40℃ for 3h, then salt out , Filtered and dried to obtain the finished product. The latest research results can be found in Active Orange X-GN.
