Summary:chemical technology. SUBSTANCE: invention relates to method of synthesis of cyclohexane oxidation substances by catalytical liquid-phase oxidation with oxygen-containing gases. Liquid cyclohexane is passed by countercurrent procedure through reaction zone which is separated for some communicating chambers by perforated plates. Oxygen-containing gas is added along reaction zone through nozzle holes that are uniformly distributed by cross section. As result, no formation of continuous gaseous phase in reaction zone is occurred. Distances of gas feeding are 0.1-3-fold diameter of reaction zone being gas is added to reaction zone where oxygen from preceding addition is not consumed completely. Temperature in reactor is 120-180 C, pressure is 5-30 bars. EFFECT: decreased formation of by-side compounds, increased productivity of reactor. 10 cl, 1 tbl, 2 ex
