Abstract

Abstract: Isomerization of α-pinene was studied over phosphotungstic acid and activated carbon supported phosphotungstic acid catalysts.Influences of the reaction condition on conversion and selectivity of products were investigated.The experimental results show that solvents and temperature have obvious influence on activity of the catalyst and that HPW catalyst has both high catalytic activity and selectivity even at lower temperature to produce the expected camphene and limonene isomers.After being supported on activated carbon, the catalytic activity and stability of phosphotungstic acid have been improved greatlty and the catalyst can be reused.

Key words: pinene, phosphotungstic acid, activated carbon
