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 produc

b) the output from the reaction zone is treated with oxygen in the presence of acidic aqueous cobalt(II) salt solution, with the cobalt catalyst being decomposed to form cobalt(II) salts and these being backextracted into the aqueous phase; and the phases are subsequently separated,
c) the aqueous cobalt(II) salt solution is recirculated in unchanged form to step a), wherein the cobalt(II) salt solution has a concentration of from 1.1 to 1.
