| Abstract: | Pinene isomerization was studed over active carbon supported silicotungstic acid catalyst. The effect of reaction temperature and time, mixture ratio and solvent on isomerization conversion and selectivity were examined. The results show that with the increase of the reaction temperature and time and the reduction of the mixture ratio, the conversion of α Pinene increases. The isomerization and ethoxylation of α Pinene can occur in ethanol medium. The main products are camphene, limonene and α turpinyl ethyl ether. The total ether selectivity is approximately 50%. |
