FIELD: chemistry. ^ SUBSTANCE: invention refers to method of aldehydes C3-C21production, consisting that olefins are hydroformylated with the catalyst system added as containing rhodium, polyphosphide ligand of general formula: where k+mëÑ2, and optionally k=0 or m=0; X is hydrocarbon radical including 1 to 50 carbon atoms; Z is hydrocarbon radicals identical or different in fragments m including 2 to 30 carbon atoms; Y is hydrocarbon radicals identical or different including 1 to 30 carbon atoms, and phosphoprous-containing promoting ligand chosen of monodentate organophosphine, bidentate organodiphosphine and organophosphite. Then product aldehydes are separated from the dissolved catalyst by distillation. The mole ratio of promoting ligand/Rh is 1-50. The disclosed method allows for radioselective production of linear aldehydes C3-C21. ^ EFFECT: reduced initial charge of polyphosphite ligand with lowered deactivation. ^ 8 cl, 8 tbl, 25 ex |
