【Abstract】 Isomerization of β-Pinene catalyzed by S₂O₈^2-/ZrO₂ nanosolid superacid has been studied.The results showed that the catalyst have very high-activity and selectivity.The primary product of isomerization is camphene and by-products are limonene,carene,tricyclene and β-terpinene,p-cymene etc.The optimum conditions for β-Pinene isomerization are as follows: reaction temperature 70 ℃,reaction time 4 h and the ratio of solid superacid to β-Pinene 0.03（mass ratio）,under these conditions β-Pinene conversion is 100% and camphene selectivity is 61.90%.更多还原
