4-Chlorophthalic anhydride Usage And Synthesis

Uses

4-chlorophthalic anhydride is an important monomer synthesis of polyimide and polyimide is considered to be the highest tolerance has been industrialized in the polymer and the shape and chemical stability of other materials can not like the outburst strength, wear resistance and extreme temperatures, excellent, has been widely used in aviation, aerospace, microelectronics and atom to the field of high technology. 4- of 4-chlorophthalic anhydride is mainly used in the synthesis of diphenyl ether dianhydride anhydride, two single and two double ether, thioether dianhydride anhydride two, two, and two amine polymerization ring was a series of polyimide engineering plastic with excellent performance. 4- of 4-chlorophthalic anhydride is not only the ideal raw material for the synthesis of various intermediates of polyimide, and can be used as a drug or pesticide.
