반응 단계
In a single-vessel process for preparing 2-acetaminonaphthalene-6-sulfonic acid of high purity by sulfonating 2-hydroxynaphthalene with concentrated sulfonic acid, converting the 2-hydroxynaphthalenesulfonic acid formed thereby with ammonia in the presence of ammonium hydrogensulfite into 2-aminonaphthalene-6-sulfonic acid (Bucherer reaction) and N-acetylating the said 2-aminonaphthalene-6-sulfonic acid to give 2-acetaminonaphthalene-6-sulfonic acid, the improvement which comprises:
