It is a white solid at room temperature.Contentshide 1 Preparation 2 Uses 3 Reactivity 4 Natural occurrence 5 References edit PreparationPhthalimide can be prepared by h
4、eating phthalic anhydride with aqueous ammonia giving 95-97% yield. Alternatively, it may be prepared by fusing the anhydride with ammonium carbonate.edit UsesPhthalimide is used in plastics, in chemical synthesis, and in research.edit ReactivityIt forms salts with various metals such as potassium a
5、nd sodium due to its high acidity caused by the electrophilic carbonyl groups attached to the nitrogen atom, and can be made by reacting phthalimide with metal carbonates. Potassium phthalimide, made by reacting phthalimide with potassium carbonate in water at 100C, is used in the Gabriel synthesis
