PROBLEM TO BE SOLVED: To obtain an aromatic compound having hydroxyl group in a high selectivity by performing a catalytic oxidation of an aromatic compound in the presence of a porous glass using a gas containing dinitrogen monoxide at a prescribed temperature. SOLUTION: This method for producing an aromatic compound having hydroxyl group, is to perform a catalytic oxidation of an aromatic compound in the presence of a porous glass by using a gas containing dinitrogen monoxide at 100-800 deg.C. As the aromatic compound, the use of benzene is preferable. The gas containing dinitrogen monoxide preferably contains 5-100 vol.% dinitrogen monoxide and 0-95 vol.% other gas (poreferably air, oxygen, nitrogen, a rare gas, carbon dioxide, steam, ammonia or their mixture). It is preferable that the mean value of the pore sizes of the porous glass is 0.1-1.0 nm, the total surface area thereof is at least 50 m2/g in its dry state, and at least 50 wt.% thereof consists of oxides of elements belonging to the 3rd main group, 4th main group, or the like, of the Periodic Table.
