ABSTRACT:
Disclosed is an extraction process for the recovery of high-boiling aldehydes produced by the rhodium-catalyzed hydroformylation of olefins in the presence of a hydroformylation solvent. The extraction process involves intimately contacting a hydroformylation product solution comprising (i) a high-boiling aldehyde, (ii) hydroformylation catalyst components comprising rhodium and an organophosphine compound, and (iii) a hydroformylation solvent with an extraction solution comprising a primary alkanol and water to form a 2-phase mixture. The phases are separated to obtain a hydroformylation solvent phase containing catalyst components and an alkanol/water phase containing the high-boiling aldehyde.
