Abstract
A hydroformylation catalyst having excellent catalytic activity and stability, a composition including the hydroformylation catalyst, and a method of preparing an aldehyde using the hydroformylation catalyst, wherein, when hydroformylation of an olefin compound is performed in the presence of the hydroformylation catalyst to prepare an aldehyde, the normal/iso (n/i) ratio of the prepared aldehyde is lowered, and synthesis gas yield is increased.
