Oxidation of Cyclohexylamine to Cyclohexanone Oxime Catalyzed by Al2O3-SiO2
Abstract:
The oxidation of cyclohexylamine catalyzed by Al2O3-SiO2 catalyst was carried out under mild conditions.The effects of solvent amount,catalyst amount,reaction time and reaction temperature on the reaction were investigated.Under the conditions of V(acetonitrile):V(cyclohexylamine)=3:1,31.0% mass fraction of catalyst,reaction temperature of 75℃,and reaction time of 5 h,the conversion of cyclohexylamine reaches up to 100% and the selectivity for cyclohexanone oxime is 83.6%.A reaction mechanism is proposed.
