실험 절차

A suspension of 11.95 g of 6-amino-4-hydroxy-2-naphthalenesulfonic acid in 200 ml of water was adjusted to pH 8.0 with aqueous 5N sodium hydroxide, then 12.17 g of sodium acetate trihydrate was added to the stirred mixture followed by 15.06 g of p-nitrobenzenesulfonyl chloride. The mixture was stirred vigorously under nitrogen at room temperature for 16 hours producing a yellow solid. The mixture was filtered and the solid was washed with water, ethanol and then ether and dried in vacuo and gave 12.07 g of 4-hydroxy-6-p-nitrobenzenesulfonamido-2-naphthalenesulfonic acid sodium salt as a yellow solid.
