Abstract

The invention relates to a process for the continuous preparation of aldehydes and/or alcohols having at least 6 carbon atoms by multistage hydroformylation of olefins or olefin mixtures having at least 5 carbon atoms in the presence of unmodified cobalt complexes, in which at least two reactors are operated at different temperatures in the temperature range from 100 to 220° C. and pressures of from 100 to 400 bar, which is characterized in that
