Abstract

Hydroperoxides of secondary alkyl aryl compounds are converted into phenols and ketones by decomposing the hydroperoxide with a catalytic amount of sulphur trioxide, viz. 0.001 to 1 per cent by weight (based on the total reaction mixture), the reaction being carried out in a polar organic solvent, such as a ketone. The solvent may contain 0.2 to 1 per cent by weight of water. In Example (2), metal di-isopropyl benzene dihydroperoxide is prepared by oxidation of meta di-isopropyl benzene with air; and the dihydroperoxide is crystallized out by adding toluene. The dihydroperoxide is then dissolved in acetone having a water-content of 0.3 per cent. A dilute solution of sulphur trioxide in acetone is also prepared. The two solutions are separately pumped through two reactors connected in series. The reactors are maintained at 58 DEG C.; and the residence-time of the mixture therein is 10 minutes. After adding magnesia to the effluent, it is filtered, and fractionally distilled to separate resorcinol. Example (4) relates to the conversion of cumene hydroperoxide into phenol. Specification 684,039 is referred to.
