ABSTRACT:
A process is described for the preparation of cyclohexanone by oxidation of cyclohexane in the liquid phase with oxygen or a gas containing oxygen, under conditions so that the oxidation product contains cyclohexyl hydroperoxyde, followed by catalytically hydrogenating the said oxidation product with a hydrogen gas-containing stream in a hydrogenating zone, whereby the said cyclohexyl hydroperoxide is converted substantially to cyclohexanol, and catalytically dehydrogenating the said cyclohexanol together with cyclohexanol produced in the oxidation reaction to cyclohexanone and hydrogen, separating the said cyclohexanone and passing at least part of the resulting hydrogen containing gas stream to the said hydrogenating zone to effect the said hydrogenation of the oxidation product.
