Selective oxidation of limonene over γ-Al₂O₃ supported metal catalyst with H₂O₂

Liquid phase oxidation of limonene by hydrogen peroxide over the C_eO₂ and Fe₂O₃ catalysts supported by γ-Al₂O₃ was reported. Etly acetate and acetone were used as solvent to investigate the effect of the solvent on the oxidation reaction. The experiments were carried out at 80°C The conversion of limonene and the selectivities of the carvone were calculated during the 10h reaction time. According to experimental results, maximum conversion of limonene and product selectivity of carvone were obtained with C_eO₂-γAl₂O₃ catalyst as 85% and 41%, respectively end of the 10 h reaction. The XRD analysis of the C_eO₂-γAl₂O₃ catalyst were performed.
