| Abstract: | 1,3-di(4-methyl benzoyl)benzene(DMBB) was prepared by Friedel-Crafts polycondensation of isophthaloyl chloride(IPC) with toluene.The yield of DMBB was 85%.DMBB was subsequently oxidated into intermediate,1,3-di(4-carboxyl benzoyl)benzene(DMBA) with 96% yield in the presence of KMnO4 in aqueous solution of pyridine and water.Then the reaction of DMBA with sulfurous oxychloride yielded polymerization-grade monomer 1,3-di(4-formyl chloride benzoyl)benzene(DMBC) with 91% yield.The overall yield of the three-ste... |
