PURPOSE: A hydroformylation method is provided to restrain catalytic poisoning by inserting a specificα,β-unsaturated carbonyl compound into hydroformylation, thereby increasing reaction yield and restraining the decomposition of ligand and catalyst. CONSTITUTION: A hydroformylation method comprises a step of manufacturing aldehyde by reacting olefin-based unsaturated compound with carbon monoxide and hydrogen under the presence of transition metal-phosphite complex catalyst which is formed from transition metal and phosphite ligand, and additionally injecting one or more compounds in chemical formula 1-4 at the same time. In chemical formulas R' and R" is respectively C1-3 substituted or unsubstituted alkyl, R'" is C6-12 substituted or unsubstituted aryl, Ra is hydrogen, Rb is C6-12 substituted or unsubstituted aryl, Rc is hydrogen or alkyl, Rd and Re is respectively C6-12 substituted or unsubstituted aryl group, and Rf and Rg is respectively and independently hydrogen or alkyl. |
