What Is Imide?
Imides are compounds characterized by the presence of a nitrogen atom bonded to two carbonyl groups. Some imides are based on ammonia, with the nitrogen atom attached to a hydrogen atom and two carbonyl groups. Others are derived from a primary amine backbone, where the nitrogen atom is bonded to any substituent and two carbonyl groups.
Polyimide, a polymerized form of imide, is often created by reacting imide with aromatic compounds. Polyimide is known for its excellent heat resistance, durability, and industrial applications.
Uses of Imide
The primary use of imides is in the production of polyimide. Polyimide stands out among other polymers for its superior heat resistance, durability, chemical resistance, and low dielectric constant. It is commonly used in electronics as a stress buffer to protect wiring and insulation layers from heat and irritation and as an insulator inside mobile devices.
Phthalimide, another important imide, and its derivatives like potassium phthalimide are used to synthesize amines. Alkyl phthalimide, a compound with alkyl groups, serves as a raw material for producing artificial sweeteners like saccharin and azo dyes.
