    • A process for preparing hydroformylation products of olefins having from 2 to 8 carbon atoms comprises a) feeding a hydrocarbon feedstock into a cracking/dehydrogenation zone and subjecting it to thermal and/or catalytic cracking and/or dehydrogenation to give an olefin-containing cracker gas, b) subjecting the cracker gas or fractions thereof to a fractionation to give at least one Ci-olefin-enriched hydrocarbon stream and at least one Ci-olefin-depleted hydrocarbon stream, c) feeding the Ci-olefin-enriched hydrocarbon stream together with carbon monoxide and hydrogen into a hydroformylation zone and reacting it in the presence of a hydroformylation catalyst, d) separating a stream consisting essentially of unreacted Ci-olefin and saturated Ci-hydrocarbon from the output from the hydroformylation zone, e) recirculating at least part of the stream consisting essentially of unreacted Ci-olefin and saturated Ci-hydrocarbon to step b), where i is an integer from to 8. The proposed coupling of the hydroformylation with, for example, a steam cracker allows complete hydroformylation of the olefins produced without olefin losses via the waste gas.

    • 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.

    • 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.
