Abstract
The present invention relates to a catalyst composition including a phosphorous-based ligand, and a hydroformylation method using the catalyst composition. More particularly, the present invention relates to a catalyst composition, which includes two different kinds of monocoordinated phosphine ligands and a transition metal catalyst, and a hydroformylation method using the catalyst composition. In accordance with the present invention, a catalyst composition lowering a selection ratio of normal aldehyde to iso aldehyde (n/i ratio), which are generated during hydroformylation of an olefinic compound, and exhibiting superior catalytic activity and stability, and a method of hydroformylating an olefinic compound using the catalyst composition are provided.
