摘要： 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).

摘要： 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.
