| Abstract: | First time,TiO 2/S 2O 2- 8 solid superacid was used to catalyze the isomerization of longifolene.The effects of preparation methods,impregnation concentration,calcination temperature,reaction temperature,reaction time,amount of TiO 2/S 2O 2- 8 catalyst on catalyst activity of longifolene were studied and the suitable condition of isomerization of the catalyst were obtained.The results indicate that the solid superacid has fair catalytic activity and selectivity on longifolene isomerization. |
