Oxygen → Hydroperoxide,1,1'-[1,3-phenylenebis(1-methylethylidene)]bis-

Participants

Reaction Steps

The objects of the present invention are achieved by a process in which diisopropylbenzene, comprised of m-diisopropylbenzene diisopropylbenzene and less than 6% o-diisopropylbenzene, is oxidized under anhydrous, non-alkaline conditions with oxygen or air at about 85° C.-95° C. in a continuous process. The hydroperoxidation method of the present invention produced a 92.8% yield of m-diisopropylbenzene dihydroperoxide (m-DHP) and m-diisopropylbenzene hydroxyhydroperoxide (m-HHP), of which approximately 75% was m-DHP and 25% was m-HHP. Furthermore, the composition remains substantially the same through at least ten cycles of batch operations.
