    Abstract: PROBLEM TO BE SOLVED: To provide a hydroformylation method for producing a decyl alcohol isomer mixture in which the hydroformylation of butadiene to provide an aldehyde mixture, the separation of the obtained aldehyde mixture from the reaction product, the condensation of the aldehyde mixture and the separation of an aldol mixture, during the formation of the aldol mixture, and the hydrogenation of the aldol mixture to provide a decyl alcohol isomer mixture are included, and by which the butadiene can be industrially readily converted to a desired alcohol. SOLUTION: Butadiene is subjected to hydroformylation in the presence of water and water-soluble rhodium-, alkyl- or aryl-diphosphine-complex as a catalyst at 70-150 deg.C under 0.4-30 MPa pressure. The volume ratio of the aqueous phase to the organic phase is (0.1-100):1, the rhodium concentration in the aqueous catalytic solution is 20-2,000 ppm, and the phosphine of 4-100 mol per mol rhodium is used.
