Percent Composition: C 58.53%, H 4.91%, N 17.06%, O 19.49%
Literature References: Prepd from phthalic anhydride and anhydr ammonia in benzene: Dominikiewicz, Arch. Chem. Farm. 3, 141 (1937).
Properties: Minute crystals, mp 228° (commercial grades mp 221- 223°). Melts with decomposition to NH3 and phthalimide. Slightly sol in cold water, methanol. More sol in hot solvents. Heat of combustion 921.7 cal/mol. Boiling of aq or alcoholic solns produces NH3 and phthalimide. The presence of acids accelerates decompn.
