Claim 13:
14. The process according to claim 1, wherein the reactor is started up after regeneration of the hydroformylation catalyst, wherein the process is characterized in that
a gaseous feedstock mixture comprising C2- to C8-olefins to be hydroformylated together with a synthesis gas mixture is introduced into the reactor, and
the composition of the feedstock mixture and/or the composition of the synthesis gas mixture is varied in two or more steps at a constant volume flow rate in that the proportion of C2- to C8-olefins to be hydroformylated in the feedstock mixture and/or the proportion of synthesis gas in the synthesis gas mixture is increased in a stepwise manner,
wherein a maximum conversion of the C2- to C8-olefins used of 40 to 90% during the entire start-up is not exceeded.
