In the present invention, there is disclosed a multistage cobalt- or rhodium catalyzed hydroformylation of olefins containing 6 to 24 carbon atoms to alcohols comprising in each stage: a) hydroformylating olefins having a carbon atom content of 6 to 24 carbon atoms in the presence of a cobalt- or rhodium catalyst in a reactor to the point of conversion of olefin reactant to product of 20 to 98 percent; b) removing the catalyst from the resulting liquid discharged from the reactor; c) separating the resulting liquid hydroformylation mixture into a low-boiling fraction comprising olefins and paraffins, and a bottoms fraction comprising aldehydes and/or alcohols; and d) reacting the olefins present in the low-boiling fraction in subsequent process stages comprising steps a), b) and c), and combining the bottoms fractions of process steps c) of all process stages. |
