Myrtenic aldehyde is made by using α-Pinene catalytic oxidation through homogeneous reaction.The kinetics of α-Pinene catalytic oxidation reaction in the presence of complex Catalyst SeO 2-V 2O 5 has been studied by the method of initial concentration differentiation combined with the isolation method. The kinetic equation induced from experiment results is as follows r = k [ C α] 2[ W SeO 2 ] =0 014 3exp(-0 31/ T )[ C α] 2[ W SeO 2 ]. The reaction velocity is related to concentration of α-Pinene amount of main catalyst and reaction temperature.
