FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing cyclohexanone and cyclohexanol, as well as an apparatus for realising said method. The disclosed method involves processing a reaction liquid containing cyclohexane, cyclohexanone, cyclohexanol, cyclohexyl hydroperoxide and organic acids from a cyclohexane oxidation step, and involving cooling the reaction liquid, neutralisation thereof with an alkali, separation into a first aqueous-alkaline layer and a first organic layer, decomposition of the cyclohexyl hydroperoxide in the presence of a catalyst and an alkali, and separation of a second aqueous-alkaline layer, return thereof into the cyclohexyl hydroperoxide decomposition unit and for neutralisation, and separation of a second organic layer for distillation of cyclohexane with extraction of cyclohexanone and cyclohexanol and returning cyclohexane to its oxidation step. After cooling, the reaction liquid is washed from organic acids by feeding water into its stream followed by separation of the aqueous-acidic layer and cleaning thereof via extraction with cyclohexane and returning the extract into the stream of the reaction liquid, and distillation of the raffinate with separation of the aqueous-acidic runoff and distillate which is fed into the stream of the reaction liquid, and the prepared organic layer is fed to the neutralisation step in form of a mixture of the washed reaction liquid and extract containing cyclohexyl hydroperoxide.

EFFECT: invention enables to obtain the end products using a simple and cheap method.
