실험 절차

1.48 g (10.0 mmol) of phthalic anhydride and 0.723 g (3.67 mmol) of hydroxylammonium phosphate were pulverized, mixed and, following the addition of 2 ml of water, heated at a bath temperature of 130° C. for about 1½ hours. The cooled lemon-yellow reaction mixture was diluted with water, and the solid was filtered off with suction, washed with water and dried at 50° C. The yield was 1.39 g (86%).
