    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.

    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: 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: Essentially monounsaturated polyalkylenes having from 30 to 700 carbon atoms are continuously hydroformylated by a process in which i) a hydroformylation-active cobalt carbonyl catalyst is prepared from a catalyst precursor dissolved in an aqueous phase in the absence of the polyalkylenes, ii) the polyalkylenes are hydroformylated by means of synthesis gas in the presence of the cobalt carbonyl catalyst in a reaction zone, iii) the cobalt carbonyl catalyst is separated from the output from the reaction zone with at least partial reformation of the catalyst precursor and the catalyst precursor is recirculated to step i).
