Versuchsvorschrift

To a warm solution of 23.8 g of 80.5% 8-amino-1,3,5-naphthalenetrisulfonic acid in 25 ml of water and 25 ml of 5 N sodium hydroxide are slowly added 125 ml of absolute ethyl alcohol with vigorous stirring. The mixture is cooled to room temperature, is filtered and washed with 50 ml of 80% aqueous ethyl alcohol, then ethyl alcohol and ether. The material is dried overnight at 110° C. to give 21.0 g of 8-amino-1,3,5-naphthalenetrisulfonic acid trisodium salt as a powder.
