Catalyst composition for hydroformylation of an olefin-based compound, comprising: (a) a triaryl phosphine ligand represented by the following chemical formula 1; (b) a phosphine oxide or phosphine sulfide ligand represented by the following chemical formulas 2 or 3; and (c) a transition metal catalyst selected from the group consisting of acetylacetonatodicarbonylrhodium [Rh(AcAc)(CO)2], and acetylacetonatocarbonyltriphenylphosphinorhodium [Rh(AcAc)(CO)(TPP)], wherein the compound based on olefins is at least one compound selected from the group consisting of ethene, propene, 1-butene, 1-pentene, 1-hexene, 1-octene, and styrene, in chemical formula 1 above, R1 to R15 are each independently of them hydrogen, a substituted or unsubstituted C1 to C5 alkyl group, and a substituted or unsubstituted C1 to C5 alkoxy group; and when R1 to R15 are substituted by substituents, the substituents are each independently nitro group (-NO2), fluorine (F), chlorine (Cl), bromine (Br), and silyl group (-SiR3; in this case , R is hydrogen, alkyl group or alkoxy group). in the above chemical formula 2, R16 and R17 are each independently a substituted or unsubstituted C1 to C20 alkyl group; substituted or unsubstituted C5 to C20 cycloalkyl group or cycloalkenyl group; C6 to C36 substituted or unsubstituted aryl group; substituted or unsubstituted hetero C1 to C20 alkyl group; C4 to C36 substituted or unsubstituted heteroaryl group; or C4 to C36 substituted or unsubstituted heterocyclic group, in this case, heteroalkyl group, heteroaryl group, and heterocyclic group each independently have at least one atom selected from the group consisting of N, O and S. |
