Abstract

Cyclohexanone is prepared by vapour phase dehydrogenation of cyclohexanol derived from a cyclohexane oxidation product, over a zinc oxide catalyst. The cyclohexanol feed used preferably contains 85-95% cyclohexanol, the remainder being cyclohexanone and incidental impurities and the feed is preferably washed with aqueous alkali before being subjected to dehydrogenation e.g. at 325-425 DEG C. Examples are given and the purity of the product and selectivity of the catalyst compared with the purity and selectivity in brass catalysed dehydrogenations.
