Title: Improvements in the production of cyclo-octane
IPC: C07C5/03
Filed: 1957-11-06
Abstract: A catalyst for hydrogenating cyclo-octatetraene (see Group IV (b)) comprises copper, nickel and either chromium or manganese supported on a neutral, finely-pored support; such a support must have very many micropores and very few macropores and have a pH when suspended in water between 5 and 9.  The support should also preferably have a large internal surface area.  The catalyst may contain, by weight, 10-20 per cent nickel, 1-8 per cent copper and 0.5-5 per cent manganese or chromium; the following data is given for a suitable support:-  Aluminium oxide: Many micropores, few macropores. Internal surface area: without catalyst: 277.4 m.2/g. with 20 per cent catalyst: 117.5 m.2/g. Mean pore radius: without catalyst: 37.6  . with 20 per cent catalyst: 58.7  . Micropore volume: without catalyst: 0.497 cc./g. with 20 per cent catalyst: 0.255 c.c./g. Macropore volume: without catalyst: 0.024 c.c./g. with 20 per cent catalyst: 0.090 c.c./g.  Some details are also given of a chabazite (natural zeolite), a calcium aluminium silicate (synthetic zeolite) and an amorphous (synthetic) zeolite.  Reference is also made to sodium zeolites. The catalyst can be regenerated by treatment with hydrogen at 300-380 DEG  C.ALSO:Cyclooctane is produced by the catalytic hydrogenation of cyclooctatetraene at elevated temperature and pressure within the pH range of 5 to 9, the catalyst being a nickel-copper catalyst containing manganese or chromium supported on a neutral, finely-pored carrier (see Group III).  Suitable conditions are 50-200 DEG  C. and 50-350 atmospheres.  A solvent or diluent may be used such as C6-C8 paraffins, cycloaliphatic hydrocarbons such as cyclohexane and methylcyclohexane, or aromatic or alkyl-aromatic hydrocarbons such as benzene or toluene which are not hydrogenated under the reaction conditions. Cyclooctane is a useful diluent in large scale operations.  In batch processes 3-20 per cent of catalyst by weight of the cyclooctadiene is used and hydrogen pressure maintained as absorbed.  In continuous processes the hydrogen is circulated thereby aiding in keeping the reaction temperature down, fresh hydrogen being added continuously.  The hydrogen and hydrocarbon feed are fed concurrently downwardly through a fixed catalyst bed in a high pressure trickling chamber.  The catalyst may contain 10-20 per cent nickel, 1-8 per cent copper and 0.5-5 per cent of manganese or chromium supported on alumina, chabazite (natural zeolite) or a synthetic amorphous or crystalline zeolite (e.g. sodium or calcium aluminium silicate).  The catalyst can be regenerated by treatment with hydrogen at 300-380 DEG  C.
