In a process for the production of hydroperoxides by the oxidation of an aromatic hydrocarbon having at least one tertiary carbon atom with oxygen or an oxygen containing gas in the presence of an aqueous alkaline solution, an improvement is made in that the oxidation is effected in an emulsion phase which is caused by powerfully mixing all or a part of the materials to be brought into the oxidation reaction only by the aid of the hydroperoxides formed in the reaction, whereby enhancing the reaction rate with safety.
