This invention is fine chemical technology, involving the use of cyclohexane oxidation preparation of cyclohexanone production process and reducing coarse mixture of cyclohexanone and cyclohexanol light component method and aids. In the light of feed add a concentration of 5 ~ 20 of KA oil additive potassium hydroxide solution and some light component in condensation under alkaline conditions, restructuring, thereby reducing KA light component content in oil, reducing the expense of the top discharge volume, thereby reducing the wastage of cyclohexanone. With an annual output of 60,000 tons of cyclohexanone operation accounting year to reduce the loss of cyclohexanone capacity of 300 tons.
