| Abstract: | Acid Red S-JL was synthesized .After the diazotization of 2-amino-4-chlorophenol,the product coupled with 1-（4＇-Sulfophenyl）-3-Methyl-5-Pyrazolone and 1-Phenyl-3-Methyl-5-Pyrazolone yielding azo compoundⅠ and Ⅱ respectively .Azo compound Ⅰ reacted with chromium trioxide gaining metallined compound Ⅲ. The asymmetric metalline dye Acid Red S-JL was obtained by the reaction of the compound Ⅲ with the compound Ⅱ in alkalescent condition. This essay introduced the molecular structure and synthetic route of the dyestuff. |
