英文摘要：

Oxidation of β-pinene with aqueous hydrogen peroxide as oxidant catalyzed by benzoic acid oxovanadium, which was synthesized by vanadium pentoxide, was successfully carried out under mild conditions. The effects of reaction conditions such as dosages of catalyst, H2O2 , solvent and H2O on this reaction were investigated. The optimal reaction conditions were： V（acetone） ： V（β-pinene） 4 ： 1, benzoic acid oxovanadium mass fraction 5 % , n（ H2O2 ） ： n（β-pinene） 2 ： 1, reaction temperature 30 ℃. Reacting for 24 h under the optimal conditions, conversion of β-pinene can reach up to 56.2 % and selectivities of major products nopinone and vebenone were 42.8 % and 35.5 % respectively.
