<p>A process for preparation of cyclohexanone oxime which comprises step (1) of subjecting a starting material selected from the group consisting of cyclohexanol, cyclohexanone, and mixtures of both to amination to thereby obtain cyclohexylamine and step (2) of subjecting the cyclohexylamine to partial oxidation to thereby obtain cyclohexanone oxime, characterized in that by-products (α) formed in step (1) and/or by-products (β) formed in step (2) are recycled to the amination system of step (1).</p> |
