ABSTRACT:
Aromatic hydrocarbons and particularly phenols and phenol ethers can be hydroxylated by reacting the aromatic compound with hydrogen peroxide in a reaction medium comprising trifluoromethanesulfonic acid. High yields of hydroxylated aromatic compounds are obtained by this process which avoids the use of extremely corrosive and difficult to handle agents. Phenol is hydroxylated predominantly to hydroquinone by this process.
