Composition including hydroformylation catalyst

#The present disclosure relates to a hydroformylation catalyst, a composition including the hydroformylation catalyst, and a method of preparing an aldehyde using the hydroformylation catalyst, and more particularly, to 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.

#A hydroformylation reaction, in which various olefins are reacted with carbon monoxide (CO) and hydrogen (H2), commonly called synthesis gas, in the presence of a homogeneous organometallic catalyst and a ligand to prepare linear (normal) and branched (iso) aldehydes with one increase in carbon number, was first discovered in 1938 by Otto Roelen in Germany.

#The hydroformylation reaction, also known as the OXO reaction, is industrially very important in homogeneous catalytic reactions. Various aldehydes including alcohol derivatives are prepared through the OXO reaction, and the prepared aldehydes are consumed worldwide.

#Hereinafter, the present disclosure will be described in detail.

#When hydroformylation of an olefin is performed in the presence of a hydroformylation catalyst including a specified content of a particular phosphite ligand based on the content of a transition metal, preferably at a reaction temperature and a reaction pressure within a predetermined range, the normal/iso (n/i) ratio of an aldehyde was significantly lowered, synthesis gas yield was increased, and the catalytic activity and stability of the hydroformylation catalyst were found to be excellent. The present inventors confirmed the above results and completed the present invention on the basis thereof.

#The hydroformylation catalyst according to the present disclosure, a composition including the hydroformylation catalyst, and a method of preparing an aldehyde using the hydroformylation catalyst are as follows.
