Stabilization of phosphite ligands in hydroformylation process |
摘要 |
The present invention provides a hydroformylation process comprising: (1) forming a reaction mixture containing: (a) an olefinic compound, (b) hydrogen, (c) carbon monoxide, (d) a phosphite in which each phosphorus atom is bonded to three oxygen atoms and at least one such oxygen atom is bonded to a carbon atom of an aromatic ring that is adjacent to another carbon atom of said ring having a pendant monovalent group having a steric hindrance at least as great as the steric hindrance of the isopropyl group, (e) a catalytic amount of rhodium, and (f) a Group VIII metal (other than a rhodium) in an amount sufficient to reduce the rhodium-catalyzed decomposition of the phosphite during the hydroformylation process; and (2) maintaining the reaction mixture under conditions at which the olefinic compound reacts with the hydrogen and carbon monoxide to form an aldehyde. |
