A method for removing cobalt values from the crude product of a cobalt-catalyzed hydroformylation reaction wherein an overhead stripper-reactor reflux product is recycled to a location on the stripper-reactor which is capable of forming a stripping zone in the upper portion of the stripper-reactor and a reaction zone in the lower portion of the stripper-reactor. L'invention se rapporte à un procédé pour extraire les valeurs de cobalt contenues dans le produit brut d'une réaction d'hydroformylation catalysée au cobalt. A cet effet, un produit de reflux de l'appareil de stripage/réaction correspondant à la fraction de tête est recyclé vers un endroit de l'appareil de stripage/réaction propre à former une zone de stripage dans la partie supérieure de l'appareil de stripage/réaction et une zone de réaction dans la partie inférieure dudit appareil.
