Abstract: Ferric deuteroporphyrin dimethyl ester (FeClDPDME) was employed as the model catalyst to investigate the catalytic oxidation of α-pinene by molecular oxygen without any solvent and additive. The influences of temperature, time, catalyst mass ratio and molecular oxygen flow rate on this reaction were investigated. The results showed that the oxidation occurred mainly on C=C bond and allylic C-H bonds of α-pinene. The optimal conditions of this reaction were reaction temperature 80℃, reaction time 6 h, catalyst mass ratio 50 mg/kg and molecular oxygen flow rate 60 mL/min, respectively. Under these conditions the conversion rate of α-pinene and the total selectivity of C=C bond and allylic C-H bonds oxidation products reached 17.9% and 86.7%, respectively.
