| abstract |
The invention relates to a method for production of hydroformylated olefins, whereby a) an olefin-containing feed, carbon monoxide and hydrogen are fed into a first reaction zone and reacted in the presence of a first catalyst system, b) a liquid stream essentially comprising unreacted olefins and optionally saturated hydrocarbons is separated from the discharge from the first reaction zone, c) the liquid stream obtained in step b), carbon monoxide and hydrogen are fed into a second reaction zone and reacted in the presence of a second catalyst system. |
