| titleOfInvention | Improved Hydroformylation Method for Separation and Recycling of Activated Rhodium Catalysts |
| abstract | The active rhodium catalyst and impurities are separated from the hydroformylation process stream containing both the active organic rhodium catalyst and the inert organic rhodium catalyst by binding the active catalyst and impurities to an acidic ion exchange resin containing acidic groups. The purified hydroformylation stream may be returned to the hydroformylation reactor. All or part of the inert rhodium may be reactivated prior to recycling the purified hydroformylation process stream to the reactor. During the regeneration of the resin, impurities that are discarded are first removed using a neutral solvent and then an active organic rhodium catalyst is removed from the resin using an acidic solvent. The active catalyst can be rehydrogenated and returned to the hydroformylation reactor. Ion exchange resins can be prepared in which one or more acid groups are disposed in the silica backbone and the active organic rhodium complex of the hydroformylation process stream is bonded to the resin. |
