3102.----- [RUHRCHEMIE, A. G.]  [Process for the Catalytic Addition of Water Gas to Olefins.]  German Patent Appl. --, R 655, filed Jan. 9, 1943. FIAT Reel K-30, frames 8,007-8,010; PB 73,587; TOM Reel 36, bag 3,454, item 36, 4 pp.; Meyer Transl. PC-S-V, Oxo, vol. 1, ch. 6, p. 12.

In performing the catalytic addition of water gas to olefins under increased pressure at about 200°, the catalysts are dissolved in mediums, such as H₂O or aqueous solutions, that are virtually insoluble in the olefins to be reacted.  The catalyst solution is prepared by treating metals, metal oxides and/or metal salts that are able to form metal carbonyl hydrides.  other materials such as metals, oxides, salts, metalloids, kieselguhr, with organic acids and /or hydrocarbons can be present.  Whereupon, in the presence of mediums that are virtually insoluble in olefins, water gas is reacted therewith under elevated pressure and at temperatures of approximately  50°-250°.  Example:  57 kg. of a hydrocarbon mixture b. 210°-220° is mixed with 2 kg. of a reduced, finely ground Co-ThO₂-MgO-kieselguhr catalyst, and 10 1. of H₂O is added.  The mixture is then treated at 135° and 150 atm. for 45 minutes with water gas.  Hereby 8.13 gm. Co are dissolved per 1. of H₂O.  6 1. of this solution is mixed with 4.5 kg. of a hydrocarbon fraction b. 179°-200° containing 65% olefins.  The reaction mixture is then treated for 15 hr. at 135° and 150 atm. with water gas in a pressure vessel.  The reaction product separated from the catalyst solution contains 2.14 kg. of oxygenated compounds.
