Production methodprocess of 2-Aminotoluene-5-sulfonic acid powder
2-Aminotoluene-5-sulfonic acid Raw Materials Produced by sulfonation of o-toluidine. The sulphonation reaction is carried out in the solvent diphenyl sulfone and heated to 150-185°C, the reaction is carried out intensely. At the end of the reaction, the product is dissolved with alkali, the solid diphenyl sulfone is removed, and then 2-Aminotoluene-5-sulfonic acid powder is obtained by distillation, water washing, filtration, acidification, etc. The yield is 98%.
