ABSTRACT:
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.
