METHOD FOR PRODUCING AROMATIC ALCOHOLS, ESPECIALLY PHENOL

摘要

The invention relates to a process for preparing phenol derivatives by catalytic oxidation of an aromatic hydrocarbon to the hydroperoxide and subsequent cleavage of the hydroperoxide to give the phenol derivative and a ketone, wherein a compound of the formula I where R1, R2=H, aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, in each case having from 1 to 20 carbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, where R1 and R2 are identical or different radicals or R1 and R2 may be joined to one another via a covalent bond, and X, Z=C, S, CH2 Y=O, OH k=0, 1, 2 l=0, 1, 2 m=1-3; is used as oxidation catalyst in the presence of a free-radical initiator, where the molar ratio of the catalyst to the aromatic hydrocarbon is less than 10 mol %.
