Abstract

1,4-bis(4-phenoxybenzoyl)benzene was synthesized by nucleophilic and electrophilic substitution routes:(1)1,4-bis(4-chlorobenzoyl)benzene was obtained from chlorobenzene and terephthaloyl chloride(TPC).Then,the resulting compound DPOPKK was synthesized by 1,4-bis(4-chlorobenzoyl)benzene with natrium phenate,taking N-methyl-2-pyrrolidone(NMP) as solvent.(2) DPOPKK was synthesized by Friedel-Crafts acylation of terephthaloyl chloride(TPC) and excessive diphenylether(DPE) in 1,2-dichloroethane with aluminium trichloride(AlCl3) as catalyst.Its structure was characterized by FT-IR,1H NMR,Micromelting point apparatus,WAXD SEM and DSC etc.The results show that the compound is anticipated and has high purity.DPOPKK has the same crystalline diffraction peak as PEKK which is the unqiue crystallinaion characterization of PEKK.
