A single-stage process is described that includes simultaneously, in a mixture containing an olefin; synthesis gas; a cobalt catalyst in an organic phase; and an aqueous cobalt salt solution; hydroformylating the olefin, and forming and extracting into the organic phase the cobalt catalyst from the aqueous cobalt salt solution. An apparatus is also described that includes a means for carrying out the process. The process is particularly suitable for preparing aldehydes and alcohols.
