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 5N 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.
