PROBLEM TO BE SOLVED: To convert cyclohexanone oxime into the subject compound in a gaseous phase in high selectivity by using crystalline alcohol. SOLUTION: This method for producing epsilon-caprolactam comprises bringing (C) cyclohexanone oxime into contact with (A) crystalline aluminum phosphate (preferably ALPO-5) as a catalyst in the coexistence of (B) a lower alcohol (preferably at least one of methanol, ethanol and propanol) in a gaseous phase. The reaction is preferably carried out at a reaction temperature of 280-450 deg.C. |
