Study on the Synthesis of Dye Intermediate ——2-Amino-6-naphthalenesulfonyl-aniline

Amino 6 naphthalenesulfonyl aniline was synthesized from 2 amino 6 naphthalene sulfonic acid and aniline, the reaction conditions studied, and the product was characterized by IR, 1H NMR(estimate) and MS. Thus better method was provided for synthesizing the 2 amino 6 naphthalenesulfonyl aniline.
