Abstract: The olefin is introduced into the bottom zone of the hydroformylation reactor contg. a liq. reaction zone making up 60-85% of the reactor vol., at 1-40 bar and 50-140 deg. C, using Rh complex cpds. as catalysts. The gaseous reaction prods. and reaction partners are removed from the hydroformylation reactor. The reaction prods. are sepd. and most of the remaining gas is returned to the reactor as recycle gas. The novelty consists in charging 20-80 vol.% of the recycle gas to the hydroformylation reactor above the liq. reaction zone and/or below the liq. surface in the top quarter of the liq. reaction zone.
