PCT No. PCT/EP97/05740 Sec. 371 Date Apr. 14, 1999 Sec. 102(e) Date Apr. 14, 1999 PCT Filed Oct. 17, 1997 PCT Pub. No. WO98/17612 PCT Pub. Date Apr. 30, 1998In a process for preparing oxidation products of cyclohexane by catalytic oxidation with oxygen-containing gases in the liquid phase, where the gases are brought into contact essentially uniformly with the liquid cyclohexane in a reaction zone, liquid cyclohexane and the oxygen-containing gases are passed in countercurrent through the reaction zone.
