Abstract: In this paper,the reaction of α-pinene isomerization on HMC-60 catalyst was studied,and the effects of reaction temperature,reaction time and amount of catalyst were investigated.It was found that the reaction was of the first order at 140～156℃.Reaction rate constant was 4.41×10 ^-4,4.69×10^-4,5.11×10^-4 at 140,150 and 156℃ respectively.Apparent activation energy was 1.75 kJ/mol,frequency factor was 5.314×10^-4.The rate equation and the correlated relation between reaction rate constant and temperature were established.

Key words: HMC-60 catalyst, α-pinene isomerization, reaction order, apparent activation energy
