The isomerization reaction of β-pinene catalyzed by solid superacid S2O82-/TiO2 was performed. The results showed that the catalyst had strong catalytic activity and better selectivity. The main product of isomerization reaction was camphene and its by-products were limonene, carene and tricyclene etc. The factors influencing the isomerization reaction were investigated . The optimal reaction conditions were as follows:the reaction temperature 80℃, the reaction time 4h and the use level of catalyst S2O82-/TiO2 3% of the mass of β-pinene. Under the above-mentioned optimal reaction conditions, the conversion ofβ-pinene could reach 99.96%and the selectivity of camphene could reach 55.63%.
