    Abstract: 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, separating the aqueous phase from the oil phase and decomposing at least a part of the component (A) extracted in the aqueous phase.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.

    Abstract: 4,4'-dihydroxydiphenyl ether (DHDPE) is prepared by the catalytic oxidation of 4,4'-diisopropyldiphenyl ether to the corresponding dihydroperoxide, the latter being subjected to acid cleavage to provide the desired dihydroxy compound.

    Abstract: A portion of a recycle stream obtained as a result of the oxidation of an aryl tertiary alkane and containing aralkyl tertiary monohydroperoxide, substantial amounts of unreacted aryl tertiary alkane and lesser amounts of poly-oxy-functional oxidation by-products is subjected to aqueous alkaline extraction to remove at least a portion of the poly-oxy-functional oxidation by-products therefrom followed by separation of the extraction mixture into an aqueous alkaline phase and an organic phase, the organic phase being recycled to the oxidation reaction.
