Abstract
A process for producing an alkylbenzene hydroperoxide from an alkylbenzene solution containing 0.01 to 10 mmol/kg of phenols by subjecting the solution to oxidation with an oxygen-containing gas, including allowing a compound represented by formula (I) to be present in the alkylbenzene solution: wherein R, R, R, Rand Rindependently represent a hydrogen atom, an alkyl group or an aryl group and may combine with each other to form a non-aromatic ring, the molar ratio of the compound represented by formula (I) to the phenols in the alkylbenzene solution being 0.4 mol/mol or higher;is advantageous in providing economical and high-yield production of an alkylbenzene hydroperoxide.
