<p>Disclosed is a method for the hydroformylation of olefins comprising 2 to 8 carbon atoms, whereby (i) an inflow containing olefins and an added saturated hydrocarbon comprising 2 to 8 carbon atoms, as well as carbon monoxide and hydrogen, are fed into a reaction zone and reacted in the presence of a hydroformylation catalyst, (ii) a flow consisting essentially of unreacted olefins and saturated hydrocarbons is separated from the discharge from the reaction zone, (iii) said flow is separated into an olefin-enriched fraction and an olefin-depleted fraction by means of rectification, and (iv) the olefin-enriched fraction is at least partially redirected into the reaction zone.</p> |
