In producing oxygenated hydrocarbons by the catalytic addition of water gas to olefins or olefin-containing hydrocarbon mixtures, the conversion is carried out < 200°, if desired far < 200°, in presence of steam, whereby super-atmospheric reaction pressures are used.  The amount of H₂O added amounts to 0.1-100% by volume of the amount of hydrocarbon to be treated.  Example: 710 gm. of  a hydrocarbon mixture b. 41°-74° and containing 73% of olefins were mixed with 45 gm. of a reduced Co:ThO₂:MgO: kieselguhr catalyst and treated for 17 hr. with water gas in a pressure stirring apparatus.  A reaction pressure of 150 atm. and a temperature of 135° were maintained under energetic stirring.  From the resulting product, 180 gm. of oxygenated compounds were isolated, which formed oximes with hydroxylamine hydrochloride.  By operating with the addition of 35 cc. Of H₂O, the water gas treatment could be completed in 14 hrs. with production of 495 gm. of oxime-forming products.
