A method for partial oxidation of aromatic compounds such as benzene, phenol, chlorobenzene, fluombenzene, 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.

Procédé d'oxydation partielle de composés aromatiques tels que le benzène, le phénol, le chlorobenzène, le fluorobenzène, le toluène, l'éthylbenzène ou analogue, avec un déficit molaire d'oxyde nitreux par rapport à un catalyseur tel qu'une zéolithe ZSM-5 ou ZSM-11. Le procédé permet notamment de produire le phénol à partir du benzène avec une cadence de production élevée, un taux élevé de transformation d'oxyde nitreux et une sélectivité élevée vis-à-vis de la production de phénol.
