  • Process for preparing alcohols from olefins by hydroformylation and hydrogenation
    Patent number: 7154012
    Abstract: A process for preparing aliphatic alcohols that includes cobalt-catalyzed hydroformylation of olefins, treatment of a hydroformylation mixture with oxygen-containing gases in the presence of acidic, aqueous cobalt(II) salt solutions, separation of a mixture into an aqueous phase comprising cobalt salts and an organic phase comprising the aliphatic aldehydes, and hydrogenation of an aldehyde-containing organic phase wherein the organic phase and treatment with an adsorbent to separate off cobalt compounds prior to hydrogenation.
