In the reaction of olefins with CO and H2 to form oxygenated organic compounds in the presence of a Co carbonyl catalyst, a continuous process is described for removal of the catalyst from the product as metallic Co and subsequent conversion of the Co to the carbonyl in the liquid phase, with either pentane or some of the olefinic reaction mixture as solvent.  2 decobalters connected to the reaction vessel are used alternately; while 1 carries out separation of the catalyst from the reaction product, the other is treated with CO-H2 gas mixture used in the initial synthesis under conditions favorable to the formation of the carbonyl and in the presence of a solvent.  If pentane is used in this step, it is partly removed by distillation before the catalyst is returned to the reaction vessel.  Gives 2 diagrams of the apparatus.
