Patent ID: 8889916

Claim:
A catalyst composition for hydroformylation reaction comprising of: (a) one or more phosphine ligands, wherein the one or more phosphine ligands consist of one or more monodentate phosphine ligands represented by the following Formula 1; and (b) one or more transition metal catalysts: wherein R 1 , R 2 and R 3 are each independently an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 5 carbon atoms, wherein an amount of the one or more phosphine ligands is in the range of 0.8 to 2.3 wt % based on total weight of the catalyst composition, and wherein the catalyst composition selectively produces an amount of a normal aldehyde relative to an amount of an iso-aldehyde in a ratio ranging from 2.4 to 3.5.
