A process for the hydroxylation of phenols and of phenol ethers by hydrogen peroxide is described. More particularly a process for the hydroxylation of phenol by hydrogen peroxide is described. The described process can include hydroxylation of a phenol or of a phenol ether having at least one hydrogen atom at the ortho and para position of the hydroxyl group or of the ether group, by reaction of said phenol or phenol ether, with hydrogen peroxide, in the presence of an acid catalyst, wherein the reaction is carried out in the presence of an effective amount of a catalyst which is a mixture of at least two strong acids and wherein one of the acids is chosen from strong protonic acids and the other acid is chosen from superacids.
