Abstract

1368449 Cyclohexanone BAYER AG 16 Sept 1971 [17 Sept 1970] 43251/71 Heading C2C [Also in Division Bl] Cyclohexanone is prepared by vapour phase hydrogenation of phenol at a temperature of from 100‹ to 350‹ C. in the presence of catalyst which comprises palladium supported on carrier material which comprises an aluminium spinel. Palladium constitutes preferably from 0.01 to 10 weight per cent of the catalyst; aluminium spinel constitutes preferably at least 20 weight per cent of the carrier material which preferably has a surface area of from 20 to 120 m.<SP>2</SP>/g. and an average pore diameter of from 200 to 800 Angstroms and may have been prepared from alumina and a compound, for example hydroxide or salt such as nitrate or organic acid salt, of at least one metal selected from lithium, magnesium, zinc, cobalt and nickel. As exemplified, phenol is hydrogenated at 150-220‹ C. in the presence of catalyst prepared from palladium (II) chloride and carrier material which has been prepared either from gamma-alumina and lithium hydroxide or zinc nitrate or from active alumina and magnesium nitrate or cobalt (II) nitrate and in the presence of comparison catalyst prepared from palladium (II) chloride and carrier material which is alpha-alumina or gammaalumina, each catalyst being treated with hydrogen at 200‹ C. prior to use.
