| Abstract: | TiO 2/S 2O 8 2- 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 8 2- catalyst on catalytic activity of longifolene were studied and the optimal condition of isomerization were obtained. The results indicate that the solid superacid has fair catalytic activity and selectivity on longifolene isomerization. The main product was isolongifolene and the yield was about 96%. |
