FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing aldehydes via hydroformylation of terminal or internal olefins in the presence of a catalyst system containing rhodium and a mono- or polyphosphite ligand. An antioxidant is added to the reaction mixture, the antioxidant being phenols or thioureas of general formulae: 
where R denotes identical or different aliphatic or aromatic univalent radicals or hydrogen, and hydroformylation is carried out in liquid phase in a solvent medium in form of aldehyde, with rhodium concentration of 0.1-2 mmol/l, at temperature of 20-150°C and pressure of 0.2-5 MPa, wherein the amount of the antioxidant is 1-30 mol/mol phosphite ligand.
EFFECT: invention enables to obtain end products using an efficient method at low raw material costs.
