Abstract: A process for preparing hydroformylation products of propylene and for preparing acrylic acid and/or acrolein comprises a) feeding a propylene-containing feed in which from 2 to 40% by weight of propane is present and also carbon monoxide and hydrogen into a reaction zone and reacting this mixture in the presence of a hydroformylation catalyst to form hydroformylation products of propane, b) separating a stream consisting essentially of unreacted propylene and propane from the output from the reaction zone, and c) subjecting the stream consisting essentially of propylene and propane to a catalytic gas-phase oxidation in the presence of molecular oxygen to form acrylic acid and/or acrolein.

Abstract: 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.
