      3017.  ------.  [RUHRCHEMIE A. G.]  [Process for Converting Unsaturated Hydrocarbon Compounds, Particularly Olefins to Oxo Compounds or Their Reaction Products.]  German Patent Appl. --, R 598, filed Dec 30, 1941.  TOM Reel 36, bag 3,454, item 36, 2 pp.; Meyer Transl. PC-S-V, Oxo, vol. 1, chap. 3, 1948, p. 7.

            Unsaturated hydrocarbons, particularly olefins, are treated at elevated temperature and pressure with metal carbonyls and H₂ or gases containing it.  The metal carbonyl before use is dissolved or suspended in the charge and then the H₂ under high pressure and thorough stirring is passed through.  The reaction is suitably carried out under 20-200 atm. pressure and at temperatures of about 50°-250°.  The reaction takes place rapidly with good yields.  If desired, CO can be mixed with the H₂ with a corresponding saving of the carbonyl.
