Abstract: Disclosed is a method for the hydroformylation of olefins comprising 2 to 8 atoms, whereby a) an inflow containing olefins and a gas mixture containing hydrogen and carbon monoxide are fed into a reaction zone and reacted in the presence of a hydroformylation catalyst, b) the reaction product which is released from the raw hydroformylation product is redirected into the reaction zone during the extraction of a gaseous recovery flow. The inventive method is characterised in that c) the recovery flow is brought into intimate contact with a wash liquid in order to eliminate the unreacted olefins contained therein, the wash liquid being a vented hydroformylation product, and the olefin-charged wash liquid and the raw hydroformylation product are redirected for regeneration. Said inventive method enables unreacted olefins to be reclaimed to a large extent from the recovery flow.
