Abstract of the Disclosure Disclosed is a method of treating hydroperoxide mixtures, which comprises bringing an oily hydroperoxide mixture containing (A) an aromatic hydroperoxide having a hydroperoxymethyl group directly bonded to the aromatic nucleus and (B) an aromatic hydroperoxide having a 2-hydroperoxy-2-propyl group bonded directly to the aromatic nucleus into contact with an aqueous alkali solution of pH 12 to 14, separating the aqueous phase from the oil phase and decomposing at least a part of the component (A) extracted in the aqueous phase at a temperature higher than that of the contact. According to this method, the starting oily hydroperoxide mixture can be converted to a mixture in which the primary hydroperoxide content is reduced without substantial loss of the tertiary hydroperoxide. Therefore, aromatic hydroperoxide mixtures suitable for production of phenols can advantageously be proceeded.
