Hydroformylation process with doubly open-ended bisphosphite ligand |
| abstract |
A continuous hydroformylation process for producing at least one aldehyde product by utilizing a transition metal and a ligand mixture comprising an organopolyphosphite and an organomonophosphine, with improved stability of the organopolyphosphite ligand. The process involves reacting one or more olefinically-unsaturated compounds with carbon monoxide and hydrogen in the presence of an organopolyphosphite ligand and an organomonophosphine ligand, at least one of such ligands being bonded to a transition metal to form a transition metal-ligand complex hydroformylation catalyst. Surprisingly the addition of the organomonophosphine to a Rh/organopolyphosphite catalyst system did not result in a significant loss of reaction rate. |
