Abstract

Procedure for obtaining cyclohexanone, by selective hydrogenation of phenol, in the gas phase, under normal pressure or a slightly elevated or reduced pressure and under a load of 0.1-10 kg of phenol per liter of catalyst and hour, at 100- 350ºC, characterized in that the hydrogenation is carried out in the presence of palladium supported on aluminum spinel.
