FIELD: chemistry.
SUBSTANCE: claimed invention relates to method of oxydating cyclic saturated hydrocarbons, such as cyclohexane, cyclooctane, cyclododecane and decalin with oxygen to obtain alkylhydroperoxide. In accordance with invention oxidation is carried out in several successive stages to control the depth of reaction of hydrocarbon oxidation and to obtain good selectivity by alkylhydroperoxide. Gas phase forming free space of reactor, which is present at each stage, is pumped out and discharged, at least, for partial condensation. Obtained condensate or condensates are returned directly to said stages of oxidation, where concentration of oxydised products in supplied reaction medium is, at least, equal to concentration of oxydised products in returned condensate.
EFFECT: due to claimed invention of method of return to cycle reaction selectivity by ketone and alcohol is improved, with improvement of method efficiency due to reduction of quantity of "cold" hydrocarbon, supplied into certain reactors for temperature control.
