Abstract
The present invention relates to a catalyst composition for hydroformylation and a method of preparing an aldehyde using the same. More specifically, the present invention provides a catalyst composition for hydroformylation including a specific phosphite-based ligand and a transition metal compound in a specific amount range, thereby being capable of greatly lowering a use amount of an expensive transition metal compound and exhibiting excellent catalyst activity or stability. In addition, by using the catalyst composition in hydroformylation, excellent reaction efficiency may be provided and iso-aldehyde may be generated in high yield.
