실험 절차
95.0 g of formic acid are added to 15.8 g of 1,8-diaminonaphthalene and the mixture is stirred at reflux temperature (100° C.) for 1 hour. Then 200 ml of water are added, and the mixture is cooled to 15-20° C. and adjusted to a pH of 8.5 by addition of 25% strength by weight ammonia. It is cooled to 10° C. and subsequently stirred at 10° C. for 1 hour. The product which is precipitated is isolated by filtration, washed with water and dried in vacuo at 800 C.
