실험 절차

A 6.6 g portion of 8-amino-1,3,6-naphthalenetrisulfonic acid trisodium salt and 2.92 g of sodium acetate trihydrate are dissolved in 180 ml of water at 2° C. A 4.0 g portion of 3-nitrosulfobenzoic anhydride is added with stirring. A 400 ml portion of water is added and the mixture is allowed to stand 21/2 hours, filtered and the filtrate is cooled, acidified with 2-3 ml of hydrochloric acid and diluted with ethanol. The pink solid is collected by filtration, washed with 85% ethanol, ether and dried giving 2.5 g of 8-(3-nitro-2-sulfobenzamido)-1,3,6-naphthalene trisulfonic acid, tetrasodium salt.
