| Abstract: | The synthesis of ytterbium molybdovanadophosphate heteropoly complex and the application of this heteropoly complex in catalyzing phenol hydroxylation were reported. The results of onefold selectivity and high conversation were got: the conversation of phenol was 41.23%, the yield of hydroquiaone was 40.11% and the catechol hadn't been detected. The effect of temperature, solvent, medium pH value and the ratio of catalyst and phenol on the catalytic activity was also discussed. |
