PURPOSE: To produce an aromatic hydroxy compound represented by phenols under mild conditions by one step in high yield by directly oxidizing an aromatic compound with an oxidizing agent in the presence of a specific secondary alcohol and an acidic substance. CONSTITUTION: An aromatic compound is directly reacted with an oxidizing agent (preferably oxygen diluted with an inert gas) in the presence of at least one secondary alcohol selected from an aliphatic secondary alcohol and an alicyclic secondary alcohol and an acidic substance to give an aromatic hydroxy compound. Isopropyl alcohol is preferable as the secondary alcohol. Phosphoric acid, acetic acid or a heteropoly acid is preferable as the acidic substance. Benzene is preferable as the aromatic compound and phenol is preferable as the aromatic hydroxy compound. The reaction is preferably carried out in the presence of an oxidation catalyst such as a metal selected from iron, copper, palladium, platinum and titanium and its compound. |
