Versuchsvorschrift

To a solution of 13.75 g of 8-amino-1,3,6-naphthalenetrisulfonic acid trisodium salt and 4.6 g of sodium acetate trihydrate in 100 ml of water in a 500 ml baffle flask is added 4.10 g of powdered 5-nitroisophthaloyl chloride. The mixture is stirred vigorously at room temperature for one hour then is filtered through diatomaceous earth. The filtrate is concentrated to 50 ml, then warmed, acidified with 0.5 ml of concentrated hydrochloric acid and diluted with 50 ml of hot ethanol. The product is crystallized on cooling with scratching and is collected by filtration, then washed with 25 ml of 55% aqueous ethanol and 60 ml of ethanol. Additional product is obtained from the filtrate in the same manner. The total product is dried by conventional means to give 13.8 g of 8,8'-[(5-nitro-1,3-phenylene)bis(carbonylimino)]-di-1,3,6-naphthalenetrisulfonic acid hexasodium salt.
