Abstract
A method for producing cyclohexanone oxime, which comprises the steps of (1) subjecting to an amination reaction a starting material selected from the group consisting of cyclohexanol, cyclohexanone and a mixture thereof, thereby obtaining cyclohexylamine, and (2) subjecting the obtained cyclohexylamine to a partial oxidation reaction, thereby obtaining cyclohexanone oxime, wherein a by-product (α) formed in the step (1) and/or a by-product (β) formed in the step (2) are/is recycled to a reaction system of the amination reaction in the step (1).
