| Abstract: | 2-Phenylbenzimidazole was synthesized by the reaction of benzoic acid(Ⅰ) and o-phenylenediamine(Ⅱ).The reaction was accelerated by microwave irradiation and catalyzed by polyphosphoric acid(PPA).By the method of orthogonal experiment the synthesis factors influencing the reaction was optimized.n(Ⅰ)∶n(Ⅱ)=1.2∶1(Ⅰ 1.47 g,Ⅱ 1.08 g),PPA 11.0 g,the time of microwave irradiation 7 min,and the power of microwave irradiation 280 W.Under the optimal condition,the highest yield of 2-phenylbenzimidazole is 81.79%.The samples synthesized were characterized by melting point determination,IR spectrogram,1HNMR spectra and 13CNMR spectra. |
