FIELD: chemistry.
SUBSTANCE: invention relates to synthesis of hydroperoxides of alkylaromatic hydrocarbons which can serve as a source of oxygen-containing organic compounds (phenol, methylphenols, acetone, cyclohexanone etc) and as an initiator of emulsion polymerisation of unsaturated hydrocarbons. The invention discloses a method for synthesis of hydroperoxides of alkylaromatic hydrocarbons through liquid-phase oxidation of these hydrocarbons with atmospheric oxygen at atmospheric pressure, process temperature of 110-130°C, for 1-3 hours in the presence of a 4-methyl-N-hydroxyphthalimide catalyst in amount of 1.0-2.0 wt %.
EFFECT: catalyst prevents use of an initiator and alkaline additives, which considerably simplifies the process, higher conversion of initial alkylaromatic hydrocarbons while preserving high selectivity of the process.
