Abstract: The catalyst solution used in a hydroformylation process is prepared for storage by first reducing its acid concentration and/or water content, and then storing the solution under a blanket of syngas and/or an inert gas. Alternatively, or in addition to, the catalyst solution can be stored with an aqueous buffer comprising materials that will neutralize and/or absorb the acid species within the catalyst solution.

Abstract: The extraction process for removing metal salts from an organic hydroformylation reaction fluid ("HRF") prior to returning the HRF to a reaction zone of a hydroformylation process, the extraction process comprising the step of contacting the HRF with an aqueous buffer solution, is improved by contacting the HRF with water in addition to that present in the aqueous buffer solution, i.e., with added water.

Abstract: El proceso de extracción para remover sales de metal de un fluido de reacción de hidroformilación orgánico ("HRF") antes de regresar el HRF a una zona de reacción de un proceso de hidroformilación, el proceso de extracción comprende el paso de poner en contacto el HRF con una solución amortiguadora acuosa, se mejora al poner en contacto el HRF con agua además de la presente en la solución amortiguadora acuosa, es decir, con agua agregada.
