ABSTRACT:
A process for the preparation of resorcinol from diisopropylbenzene includes the steps of oxidizing m-diisopropylbenzene under anhydrous, non-alkaline conditions with oxygen, extracting m-diisopropylbenzene dihydroperoxide and m-diisopropylbenzene hydroxyhydroperoxide with dilute sodium hydroxide, re-extracting with an organic solvent, converting m-diisopropylbenzene hydroxyhydroperoxide to m-diisopropylbenzene dihydroperoxide with hydrogen peroxide, drying the product, decomposing the m-diisopropylbenzene dihydroperoxide in the presence of a catalyst selected from the group consisting of boron trifluoride, ferric chloride and stannic chloride to coproduce resorcinol and actone, and purifying the resorcinol.
