Application:
4-Chlorophthalic anhydride is an important monomer for the synthesis of polyimides. Polyimides are considered to have the highest heat resistance among the polymers that have been industrialized so far. Due to the incomparable outstanding strength, wear resistance and excellent shape and chemical stability at extreme temperatures of other materials, they have been widely used in high-tech fields such as aviation, aerospace, microelectronics and atomic energy. 4-chlorophthalic anhydride is mainly used to synthesize diphenyl dianhydride, monoether dianhydride, thioether dianhydride, diethyl dianhydride, etc., and polymerize with diamine to obtain a series of polyimide engineering plastics with excellent performance. 4-Chlorophthalic anhydride is not only an ideal raw material for the synthesis of various polyimides, but also an intermediate of drugs or pesticides.
