| 20100130792 | Catalyst Composition Including Phosphite Ligands and Hydroformylation Method Using the Same - The present invention relates to a catalyst composition that includes a bis-phosphite ligand, a poly-phosphite ligand or a mono-phosphite ligand, and a transition metal catalyst, and a hydroformylation reaction using the same. The catalyst composition has the excellent catalytic activity, and the normal/iso (N/I) selectivity of aldehyde generated by the hydroformylation reaction using the same is increased. | 05-27-2010 |
| 20100185018 | METHOD FOR THE HYDROFORMYLATION OF OLEFINS AND APPARATUS USING THE SAME - The present invention relates to a method for preparing aldehydes by reacting olefins with a synthesis gas including carbon monoxide and hydrogen, and to an apparatus therefore. More particularly, the present invention relates to a method for preparing aldehydes, characterized by spraying and supplying olefins, synthesis gas including carbon monoxide and hydrogen, and a catalyst composition into an oxo reactor through a nozzle, and to an apparatus therefore. According to the present invention, the hydroformylation efficiency can be improved, thereby obtaining desirable aldehydes with a high yield. | 07-22-2010 |
| 20100324339 | PHOSPHORUS-CONTAINING CATALYST COMPOSITION AND HYDROFORMYLATION PROCESS USING THE SAME - The present invention relates to a catalyst composition that includes a triphenylphosphine ligand, a monodentate phosphine ligand, a monodentate phosphine oxide ligand, and a transition metal catalyst, and a hydroformylation process using the same. In the hydroformylation process using the catalyst composition according to the present invention, the high catalytic activity can be obtained, and the selectivity (N/I selectivity) in respects to normal- or iso-aldehyde can be desirably controlled. | 12-23-2010 |
| 20110135544 | Apparatus For The Hydroformylation Of Olefins - The present invention relates to a method for preparing aldehydes by reacting olefins with a synthesis gas including carbon monoxide and hydrogen, and to an apparatus therefore.
