Abstract: The present invention relates to a process for preparing oxidation products from cyclohexane by a catalytic oxidation with gas containing oxygen in a liquid phase. The preparation process is characterized in that the gas is brought, at a pressure of 0.5 MPa to 3 MPa substantially regularly into contact with liquid cyclohexane in at least one reaction zone, whereby the liquid cyclohexane and the oxygen-containing gas are passed through the reaction zone in countercurrent.
