The subject of the present invention is a method for the hydroxylation of phenol by hydrogen peroxide. The method of the invention for the hydroxylation of phenol to pyrocatechol and hydroquinone in a pyrocatechol/hydroquinone ratio between 1.7 and 2.3, by reaction of the phenol with hydrogen peroxide, in the presence of a catalyst, is characterized by the fact that the reaction is carried out in the presence of an effective amount of a hydroxyaromatic sulfonic acid.
