Abstract: The liquid phase cyclohexyamine oxidation reaction to prepare cyclohexanone oxime on NaY zeolite catalyst was studied. The effects of oxidant and solvent on the reaction were investigated. The results show that NaY zeolite has the best catalytic performance when acetonitrile and hydrogen peroxide were used as solvent and oxidant respectively. An orthogonal experimental method to study the response of the optimum conditions was carried out. The results show that the effects of the amount of catalyst, the amount of solvent, reaction time, reaction temperature and amount of oxidant on the yield of cyclohexanone oxime decrease in turn. The optimal reaction conditions are as follows:0.3 g catalyst, V(cyclohexylamine)∶V(solvents)∶V(oxidants)=1∶3∶3, 65 ℃ and 2 h.

Key words: cyclohexylamine, oxidation, cyclohexanone oxime, hydrogen peroxide, NaY catalyst
