Versuchsvorschrift

A mixture of 4.35 g of 3,3'-[(5-nitro-1,3-phenylene)bis(carbonylimino)]bis[2,7-naphthalenedisulfonic acid] tetrasodium salt in 100 ml of water is heated to 57° C. A 2.07 g portion of sodium sulfide nonahydrate is added and the reaction is allowed to cool. The reaction is reheated to 67° C. and allowed to cool. The mixture is filtered and the filtrate is acidified to pH 4 using acetic acid. The mixture is heated and then filtered with added diatomaceous earth. Upon cooling the filtrate yields a solid which is filtered, washed with 50% ethanol, absolute ethanol and finally with ether giving 3,3'-[(5-amino-1,3-phenylene)bis(carbonylimino)]bis[2,7-naphthalenedisulfonic acid] tetrasodium salt.
