Abstract:
1. A hydroformylation method for preparing aldehyde by reacting an olefin-based unsaturated compound with carbon monoxide and hydrogen in the presence of a transition metal-phosphite complex catalyst produced from a transition metal catalyst and a phosphite ligand, wherein the reaction is carried out by further incorporating one or more of compounds represented by the following Formulae 1 to 4: (wherein R′ and R″ each independently represent a substituted or unsubstituted alkyl group having 1 to 3 carbon atoms, and R′″ represents a substituted or unsubstituted aryl group having 6 to 12 carbon atoms), (wherein Ra represents hydrogen, Rb represents a substituted or unsubstituted aryl group having 6 to 12 carbon atoms, and Rc represents hydrogen or an alkyl group) (wherein Rd and Re each independently represent a substituted or unsubstituted aryl group having 6 to 12 carbon atoms) (wherein Rf and Rg each independently represent hydrogen or an alkyl group).
