A method for partial oxidation of aromatic compounds such as benzene, phenol, chlorobenzene, fluorobenzene, toluene, ethylbenzene and the like, with a molar deficiency of nitrous oxide over a catalyst such as a ZSM-5 or ZSM-11 zeolite. The method is advantageous for producing phenol from benzene at high production rates, high nitrous oxide conversion and high selectivity toward the production of phenol.
