| Abstract: | 2-(1H-benzo d]imidazol-2-yl)phenol was synthesized in 85.2% yield from salicylic acid and ophenylenediamine under microwave radiation with H3PW12O40 as catalyst,L(934)orthogonal experiment was designed to obtain the optimistic experiment conditions of synthesizing 2-(1H-benzod]imidazol-2-yl)phenol,which were that n(salicylic acid):n(o-phenylenediamine) equeled 1.00:1.05(salicylic acid in reaction n(salicylic acid) equeled 0.040mol),the weight of H3PW12O40 was 0.5g,the power of microwave was 500W,radiation... |
