By well-known processes, diisopropylbenzene (DIPB) is oxidized to produce, among other products, the dihydroperoxides (DHP) and hydroxyhydroperoxides (HHP) of diisopropylbenzene, for the preparation of resorcinol. Almost all acid-catalyzed decompositions of m-DHP to resorcinol require the use of pure m-DHP. For example, U.S. Pat. No. 3,928,469 disclosed that a crude hydroperoxide mixture which is obtained from the oxidation product of m-diisopropylbenzene, and which has a composition consisting of 72% m-DHP, 20% m-HHP, and 8% others, is cleaved in a usual manner, using a mineral acid catalyst, to give only a low cleavage yield of about 70 to 73% resorcinol based on moles m-DHP used. Yet, there is no practical way to make pure DHP by the hydroperoxidation of m-DIPB and there is no economical way to separate HHP and other products from the hydroperoxidation product to obtain pure DHP.
