摘要：An improved process for the preparation of an aromatic hydroperoxide byoxidizing a hydroxyalkyl-substituted aromatic compound having at least one hydroxyalkylgroup directly bonded to an aromatic ring carbon of the aromatic compound and beingrepresented by the formula ##STR1## wherein R. sub.1 and R.sub.2 each are a lower alkylgroup, with hydrogen peroxide in the presence of an acid catalyst in a heterogeneoussystem of a water- immiscible inert aromatic hydrocarbon solvent at a reaction

temperature of up to about 70° C. while removing by-product water as an azeotrope withthe aromatic hydrocarbon solvent in the oxidation system; characterized in that saidoxidation is carried out while feeding a vapor of a water-immiscible inert aromatichydrocarbon solvent having a temperature higher than the reaction temperature but notexceeding about 90° C. into a liquid phase of the oxidation system.
