Phthalimide is an imide, which is a chemical compound with two carbonyl groups bound to a primary amine or ammonia. It is a white solid at room temperature.
Phthalimide is used in plastics
in chemical synthesis
, and in research.
It forms salts with various metals such as potassium and 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 100°C, is used in the Gabriel synthesis
of primary amines, and the Gabriel synthesis of glycine
has yields as high as 85%.
Kladnoite is a natural (mineral) analogue of phthalimide. It is very rarely found among few burning coal fire sites.
