Abstract: El objeto de la presente invencion es un procedimiento para recuperar el catalizador usado de carbonil-cobalto. Segun el cual primero se prepara, añadiendoácido, una sal de cobalto soluble en agua que, a continuacion, se precipita como hidroxido de cobalto. Luego, este hidroxido de cobalto se hace reaccionar con el N-acil-alfa-aminoácido, para cuya preparacion está previsto el catalizador de carbonil-cobalto, y la fusion de cobalto obtenida se transforma en el catalizador de carbonil-cobalto, en presencia de una mezcla formada por monoxido de carbono e hidrogeno.
