摘要： Disclosed is a method for producing propylene hydroformylation products and acrylic acids and/or acrolein, whereby a) an inflow containing propylene and 2 to 40 wt. % propane, as well as carbon monoxide and hydrogen, are fed into a reaction zone and converted into propene hydroformylation products in the presence of a hydroformylation catalyst, b) a flow consisting essentially of unreacted propylene and propane is separated from the discharge from the reaction zone, and c) said flow consisting essentially of propylene and propane is subjected to catalytic gas phase oxidation, in the presence of molecular oxygen, to obtain acrylic acid and/or acrolein.
