The present invention,n n n Hydroformylating an olefin having 6 to 24 carbon atoms at a conversion rate of 20 to 98% (a),n n n (B) removing the catalyst from the resulting liquid reactor discharge,n n n (C) separating the resulting liquid hydroformylation mixture into a low boiling point fraction comprising olefins and paraffins and a bottom fraction comprising aldehydes and / or alcohols, andn n n A process comprising the step (d) of reacting olefins present in the low boiling fraction in a further step comprising processes a), b) and c), characterized in that the bottom fractions of process (c) are combined at all stages. The present invention relates to a method for producing alcohols and / or aldehydes by multistage hydroformylation of olefins having 6 to 24 carbon atoms as a catalyst using cobalt or rhodium. |
