Abstract
Disclosed are a catalyst composition for hydroformylation of olefin compounds, comprising a specific phosphine ligand and a transition metal catalyst, and a hydroformylation process using the same. Through a hydroformylation process using the catalyst composition according to the present invention, a suitable selectivity of iso-aldehyde can be maintained, catalyst stability can be improved, the amount of used ligand can be reduced and superior catalyst activity can be obtained.
Claims10
A catalyst composition for hydroformylation comprising a monodentate phosphine ligand and a transition metal catalyst,
- wherein the monodentate phosphine ligand is at least one selected from cyclohexyldiphenylphosphine, cyclohexylditolylphosphine and cycloheptyldiphenylphosphine,
- wherein the content of the total monodentate phosphine ligand is 1.2 to 3.0% by weight with respect to the total weight of the catalyst composition, and
- wherein the catalyst composition has an aldehyde normal/iso selectivity of 1.7 to 2.1.
