Patent Abstracts

CO and H₂ react only partly under Oxo conditions with the gasoline-boiling-range olefinic products resulting from the copolymerization of secondary olefins with tertiary olefins. The unaffected olefin fraction is converted, by hydrogenation, to saturated hydrocarbons of high performance number and high sensitivity. The hydrogenation may be carried out in part during the carbonylation reaction if the carbonylation is carried out under severe conditions. The hydrogenation may then be completed using a hydrogenation catalyst, temperature 150º-700º F. and pressure >50 atm. It is best to remove first all CO from the carbonylation product by purging with H₂ or an inert gas or by washing the liquid successively with an acid and with H₂O. After hydrogenation, the gasoline and by product fractions may be separated by conventional means. 1 foreign and 6 United States patents cited.
