FIELD: pharmacology.
SUBSTANCE: invention concerns cyclic hydrocarbons, particularly obtainment of cyclohexyl-p-xylol hydroperoxide, which can serve as source for simultaneous xylenol and cyclohexanol obtainment and as emulsion polymerisation initiator for unsaturated hydrocarbons. Cyclohexyl-p-xylol hydroperoxide is obtained by cyclohexyl-p-xylol oxidation by air oxygen at atmospheric pressure in the presence of N-hydroxyphthalamide catalyst in amount of 0.5-2.5 wt % and process temperature of 110-150°C for 1-3 hours till cyclohexyl-p-xylol hydroperoxide content reaches 9.8%.
EFFECT: reduced duration of oxidation process, reduced power cost.
