Abstract
A process for the hydroxylation of aromatic hydrocarbons by hydrogen peroxide, consisting in reacting said compounds in the presence of synthetic zeolites which contain heteroatoms, both replaced and exchanged. The reaction is carried out at a temperature comprised between 80.degree. C. and 120.degree. C. and in the presence of the hydrocarbon only or in the presence of a solvent which permits, at least partially, to admix the aromatic hydrocarbon with the hydrogen peroxide.
