    • 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.
