FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method for the direct oxidation of hydrocarbon taken among cycloalkanes where their cycle comprises from 5 to 12 carbon atoms up to carboxylic acid using oxygen or oxygen-containing gas in liquid phase in solvent taken among polar protonic and aprotonic solvents in the presence of catalyst dissolved in medium. Catalyst comprises at least one soluble cobalt compound and at least one soluble chrome compound taken in the molar ratio chrome to cobalt in catalyst from 0.001 to 1000 but preferably from 0.01 to 10. Method allows preparing the end product with high selectivity up to 67.3+ACU- being without using nitric acid that excludes treatment of nitrogen oxides. EFFECT: improved method of oxidation. 11 cl
