A process has been invented for the preparation of dihydric substituted phenols which comprises reacting a solution, which is essentially anhydrous and free from hydrogen peroxide, of a percarboxylic acid in an inert organic solvent with a monohydric substituted phenol, which is derived from benzene, naphthalene or anthracene and still contains at least one free hydrogen atom in the aromatic nucleus, at temperatures from about -20° C. to about 120° C. n The dihydric substituted phenols obtained according to the invention are known, important industrial intermediate products used in the fields of photography, dyestuffs and plastics, as well as in the scent and flavoring areas. |
