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: A liquid output from a continuous hydroformylation, which comprises essentially aldehydes, high-boiling by-products, a homogeneously dissolved hydroformylation catalyst, unreacted olefins, low-boiling by-products and dissolved synthesis gas, is worked up by a process in which a) the liquid hydroformylation output is depressurized in a first depressurization stage to a pressure which is from 2 to 20 bar below the reactor pressure, resulting in separation into a liquid phase and a gas phase, and b) the liquid phase obtained in the first depressurization stage is depressurized in a second depressurization stage to a pressure which is lower than the pressure of the first depressurization stage, resulting in separation into a liquid phase comprising essentially high-boiling by-products of the hydroformylation, the homogeneously dissolved hydroformylation catalyst and small amounts of hydroformylation product and unreacted olefin and a gas phase comprising essentially the major part of the hydroformylation product, unreacted olefin and low-boiling by-products.

Abstract: The invention relates to a method for the continuous hydroformylation of polyalkenes having 30 to 700 carbon atoms and being unsaturated essentially once. The inventive method involves i) producing a cobalt carbonyl catalyst which is active for hydroformylation from a catalyst precursor which is dissolved in an aqueous phase, in the absence of the polyalkenes, ii) hydroformylating the polyalkenes with synthesis gas in the presence of the cobalt carbonyl catalyst in a reaction zone, and iii) separating the cobalt carbonyl catalyst from the discharge from the reaction zone while at least partially regenerating the catalyst precursor, and returning the catalyst precursor to step i).

Abstract: In the hydroformylation of 2-8 carbon (C) olefins (I), (a) a hydrocarbon charge is subjected to thermal and/or catalytic cracking and/or dehydrogenation; (b) the cracked gas containing olefin or a fraction is separated into streams with higher and lower (I) contents; and (c) the (I)-enriched stream, carbon monoxide and hydrogen are reacted in the presence of hydroformylation catalyst. Unreacted (I) and saturated 2-8 C hydrocarbon are separated and recycled to (b). In the production of hydroformylation products from 2-8 carbon (C) olefins (I), (a) a hydrocarbon charge is fed into a cracking/dehydrogenation zone and subjected to thermal and/or catalytic cracking and/or dehydrogenation, giving a cracked gas containing olefin; (b) the cracked gas or a fraction is separated into streams with higher and lower (I) contents; (c) the (I)-enriched stream, carbon monoxide and hydrogen are fed into a hydroformylation zone and reacted in the presence of a hydroformylation catalyst; and (d) a stream of unreacted (I) and saturated 2-8 C hydrocarbon is separated from the product stream and recycled to stage (b).

Abstract: Disclosed is a method for the hydroformylation of olefins comprising 2 to 8 atoms, whereby a) an inflow containing olefins and a gas mixture containing hydrogen and carbon monoxide are fed into a reaction zone and reacted in the presence of a hydroformylation catalyst, b) the reaction product which is released from the raw hydroformylation product is redirected into the reaction zone during the extraction of a gaseous recovery flow. The inventive method is characterised in that c) the recovery flow is brought into intimate contact with a wash liquid in order to eliminate the unreacted olefins contained therein, the wash liquid being a vented hydroformylation product, and the olefin-charged wash liquid and the raw hydroformylation product are redirected for regeneration. Said inventive method enables unreacted olefins to be reclaimed to a large extent from the recovery flow.

Abstract: Olefins having from 2 to 8 carbon atoms are hydroformylated in a process in which (i) an olefin-containing feed in which a proportion of a saturated hydrocarbon having from 2 to 8 carbon atoms is present and also carbon monoxide and hydrogen are fed into a reaction zone and reacted in the presence of a hydroformylation catalyst, (ii) a stream consisting essentially of unreacted olefin and saturated hydrocarbon is separated off from the output from the reaction zone, (iii) the stream is separated into an olefin-enriched fraction and an olefin-depleted fraction by rectification, and (iv) at least part of the olefin-enriched fraction is recirculated to the reaction zone.

Abstract: The invention relates to a method for processing a liquid discharge of a continuous hydroformylation that substantially contains aldehydes, high-boiling by-products, a homogeneously dissolved hydroformylation catalyst, non-reacted olefins, low-boiling by-products and dissolved synthesis gases. According to the inventive method a) the liquid hydroformylation discharge is expanded in a first expansion step to a pressure that is 2 to 20 bar below the reactor pressure, while the discharge is separated into a liquid phase and a gaseous phase; and b) expanding the liquid phase obtained in the first expansion step in a second expansion step to a pressure that is lower than the pressure of the first expansion step, while the liquid phase is separated into a liquid phase that substantially contains the high-boiling by-products of the hydroformylation, the homogeneously dissolved hydroformylation catalyst and small quantities of hydroformylation product and non-reacted olefins, and into a gaseous phase that substantially contains the main quantity of the hydroformylation product, non-reacted olefins and low-boiling by-products.
