ABSTRACT:
An improved process for the preparation of an aromatic hydroperoxide by oxidizing a hydroxyalkyl-substituted aromatic compound having at least one hydroxyalkyl group directly bonded to an aromatic ring carbon of the aromatic compound and being represented by the formula ##STR1## wherein R.sub.1 and R.sub.2 each are a lower alkyl group, with hydrogen peroxide in the presence of an acid catalyst in a heterogeneous system of a water-immiscible inert aromatic hydrocarbon solvent at a reaction temperature of up to about 70.degree. C. while removing by-product water as an azeotrope with the aromatic hydrocarbon solvent in the oxidation system; characterized in that said oxidation is carried out while feeding a vapor of a water-immiscible inert aromatic hydrocarbon solvent having a temperature higher than the reaction temperature but not exceeding about 90.degree. C. into a liquid phase of the oxidation system.
