ABSTRACT:
To recover a hydroformylation catalyst system containing rhodium and phosphine, the aqueous solution containing the catalyst system is mixed with acid and then extracted with an amine which is dissolved in an organic solvent. The organic phase is separated and treated with the aqueous solution of an inorganic base, thereby recovering the catalyst in essentially pure form as an aqueous solution.
