| titleOfInvention | METHOD FOR REMOVING HYDROFORMYLATION CATALYST |
| abstract | The present invention is directed to a method for removing cobalt material from a crude product of a cobalt catalyzed hydroformylation reaction using the same apparatus with two different process sequences to treat olefinic feedstocks having a wide range of carbon numbers. . Olefin-based feedstocks having 4 to 14, preferably 5 to 7 carbon atoms, are subject to cobalt by performing an acid-air cobalt demetallization step prior to the stripping step of a flash hydroformylation catalyst recovery process. While olefin-based feedstocks having 7 to 20, preferably 8 to 14 carbon atoms, can be removed, cobalt can be removed by performing the acid-air cobalt demetallization step after the stripping step. |
