| Abstract: | A series of tungstovanadophosphoric acids were synthesized and characterized with the methods of IR and NMR. The influence of V content, temperature, and Phenol/H 2O 2 molar ratio on catalytic activity was examined. The results of phenol hydroxylation with H 2O 2 in the presence of these heteropolycompounds are reported. Finally the mechanism of the reaction is discussed. |
