CA 2282148

Disclosed is a process for preparing higher oxo alcohols from isomeric olefin mixtures having from 5 to 24 carbon atoms, which comprises first hydroformylation, selectively hydrogenating the first hydroformylation stage reaction mixture, separating the hydrogenation mixture in a distillation into crude alcohol and low-boilers predominantly consisting of olefins, passing these low-boilers to a second hydroformylation stage, optionally selectively hydrogenating the second hydroformylation stage reaction mixture, optionally separating the hydrogenation mixture in one distillation into crude alcohol and low-boilers, working up the crude alcohol by distillation to pure alcohol and taking off at least some of the low-boilers to discharge saturated hydrocarbons.
