ABSTRACT:
Process for preparing aldehydes and alcohols by rhodium-catalyzed hydroformylation of olefins having 6–20 carbon atoms with subsequent separation by distillation of the output from the hydroformylation reaction into the hydroformylation products and a rhodium-containing solution and recirculation of this solution to the hydroformylation reaction, wherein the rhodium concentration of the recirculated rhodium-containing solution is 20–150 ppm by mass.
