Versuchsvorschrift

Homophthalic anhydride (20 g) and urea (60 g) were reacted at 170° C. for 1 hr. The reaction mixture was cooled, water (500 ml) was added thereto, and then the resulting precipitates were collected by filtration. The precipitate were washed with water and dried in hot air, to give 10.5 g of homophthalimide as a white powder.
