Abstract: The present invention relates to a process for the hydroformylation of 1-olefins on a rhodium-containing complex catalyst comprising a mixture of phosphorus-containing organic complex ligands in the presence of hydrogen and carbon monoxide, wherein the reaction is carried out in a solvent selected from the group of solvents having a boiling point of greater than or equal to 180° C. and less than or equal to 250° C., with a rhodium concentration of greater than or equal to 50 ppm and less than or equal to 250 ppm on catalyst complexes with at least two different complex ligands selected from the group consisting of arylphosphines and cycloalkylphosphines. Furthermore, the present invention relates to the use of the process according to the invention in the context of a two-stage hydroformylation reaction cascade.

Abstract: The present invention relates to a continuous two-phase hydroformylation process for the production of aldehydes from olefins by means of carbon monoxide, hydrogen and a transition metal catalyst in a reaction zone, the transition metal being in the form of a water-soluble catalyst complex, wherein the process comprising the following steps once or several times: a) hydroformylating by reacting the olefins, carbon monoxide and hydrogen over a water-soluble transition metal catalyst comprising water-soluble organophosphorus ligands in the reaction zone; b) reducing the concentration of the olefins in the reaction zone by reducing the olefin feed to the reaction zone and withdrawing at least a portion of the catalyst solution from the reaction system, wherein the catalyst solution withdrawal and olefin concentration reduction substeps may occur in this or reverse order, simultaneously or sequentially; c) feeding a solvent, a transition metal source and water-soluble organophosphorus ligands to the reaction sys
