| titleOfInvention | Electrolytic recovery of cobalt oxo catalysts |
| abstract | According to one embodiment of the improved process of this invention, dicobalt octacarbonyl is produced in liquid medium by subjecting an aqueous solution of a tetracarbonylcobaltate salt in the presence of a solvent for dicobalt octacarbonyl to an externally applied voltage and electrical current at a magnitude and for a time sufficient to convert at least a portion of the tetracarbonylcobaltate anion to dicobalt octacarbonyl which is efficiently extracted into said solvent, thereby producing a solvent phase which can be recovered and passed to a cobalt-catalyzed olefin hydroformylation reaction zone as the source of at least a portion of the catalyst and olefin required in the olefin hydroformylation reaction to form the corresponding aldehydes. It has been surprisingly found that such a two-phase electrolysis can be performed to efficiently provide high yields of dicobalt octacarbonyl while substantially avoiding the fouling problems associated with aqueous-phase electrolysis. |
