| titleOfInvention | Continuous hydroformylation process with catalyst substitution |
| abstract | The present invention relates to a continuous two-phase hydroformylation process for producing 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, the process comprising the following steps once or several times: a) carrying out hydroformylation by reacting the olefins, carbon monoxide and hydrogen on a water-soluble transition metal catalyst having water-soluble organophosphorus ligands in the reaction zone; b) reducing the concentration of the olefins in the reaction zone by reducing the olefin supply to the reaction zone and removing at least part of the catalyst solution from the reaction system, it being possible to carry out the sub-steps of removing catalyst solution and of reducing the olefin concentration simultaneously or successively in this order or in reverse order; c) supplying a solvent, a transition metal source and water-soluble organophosphorus ligands to the reaction system, it being possible to supply the components simultaneously or successively in any order; d) increasing the concentration of the olefins in the reaction zone by increasing the olefin supply to the reaction zone and carrying out hydroformylation by reacting the olefins with carbon monoxide and hydrogen. |
