The paper examines the contents of products of liquid-phase oxidation of cyclohexylbenzene. The study proves the existence of tertiary and secondary hydroperoxide in the oxidation products of cyclohexylbenzene. The hydroperoxides were determined directly by NMR1H-spectroscopy and indirectly by their products of reduction to ketones and alcohols. By comparing integral intensities of tertiary and secondary cyclohexylbenzene hydroperoxide proton signals, we can assume that the content of the latter is approximately 15-20% of the total hydroperoxide content present in the cyclohexylbenzene oxidation products. The general scheme of oxidative transformations of cyclohexylbenzene is compiled based on the experimental data obtained and the existing knowledge of the essence of liquid-phase oxidation of alkylsubstituted aromatic and cycloaliphatic hydrocarbons. The study shows a considerable decrease in selectivity of oxidation process when cyclohexylbenzene conversion increases up to 40-50%.
