Catalytic Activity of Dawson-Molybdovanadophosphoric in Phenol Hydroxylation with Hydrogen Peroxide

Abstract

Abstract: Molybdovanadophosphoric compounds with Dawson structure were synthesizedand used to hydroxylate phenol with hydrogen peroxide.The vibrational spectroscopy and￣(31)P NMRwere used to characterize their structures.The experimental results indicated thatthe heteropoly compounds with Dawson structure were excellent catalysts for the hydroxylation of phenol.Ahigher selectivity of single isomer can be obtained at the higher molar ratioof phenol to hydrogen peroxide.

Key words: Molybdovanadophosphoric compounds with Dawson structure, Hydroxylation ofPhenol, Hydrogen peroxide
