실험 절차

A solution of sodium nitrite (2.7 g) in water (5 ml) was added during 2 hours to a stirred mixture of 6-amino-2-naphthalenesulphonic acid (8.8 g), dilute aqueous hydrochloric acid (2.8% weight/volume, 20 ml) and water (15 ml) which had been cooled to 0° C. The mixture was stirred at 0° C. for 30 minutes and then poured onto a stirred suspension of cuprous chloride (3.96 g) in dilute aqueous hydrochloric acid (2.8%, 20 ml). The mixture was stored at ambient temperature for 18 hours. The mixture was evaporated to give 6-chloro-2-naphthalenesulphonic acid which was used without further purification.
