Abstract
A process for preparing hydroperoxides which comprises oxidizing hydrocarbon by a gas containing oxygen in the presence of a specific compound and converting them selectively to corresponding hydroperoxides. The specific compound is the compound that can capture radicals. The preferable example may be a compound selected from radicals of oxygen, nitrogen, phosphorus, sulfur, carbon or silicon or a compound that forms radicals of these in the reaction system. The present invention can be applied to oxidation of hydrocarbons including arylalkylhydrocarbons such as cumene, m-diisopropylbenzene, p-diisopropylbenzene, 1,3,5-triisopropylbenzene, isopropylnaphthalene, diisopropylnaphthalene, isopropylbiphenyl, diisopropylbiphenyl, etc.
