FIELD: chemistry.

SUBSTANCE: invention relates to a method for hydrocyanation of a hydrocarbon compound containing at least one ethylene-type unsaturated bond by reacting with hydrogen cyanide in a liquid medium in the presence of a catalyst system containing a metal element selected from transition metals and at least one organophosphorus ligand which forms a complex with the metal element. The catalyst system contains at least one monodentate organophosphite compound selected from ortho-, para-, meta-tritoluene phosphites and mixtures thereof, and at least one monodentate organophosphine compound. The molar ratio, with respect to atomic content of the metal element, of the organophosphine compound is 0.1-10 and that of the monodentate organophosphite compound is 0.1-10, wherein the molar ratio of the organophosphite compound to the organophosphine compound is 0.01-100. The organophosphine compound is a compound of general formula (I) , in which Z denotes an aromatic cyclic group containing 5 or 6 atoms, and containing an oxygen, nitrogen or sulphur atom as a heteroatom, and which is such that the phosphorus atom is bonded to a carbon atom in the alpha-position relative to the heteroatom, n is an integer from 0 to 3, m is an integer from 0 to 5, the radical R₁ denotes a hydrogen atom, a linear or branched alkyl radical which may contain heteroatoms, having 1-12 carbon atoms, a substituted or unsubstituted aromatic or cycloaliphatic radical which may contain heteroatoms, a carbonyl, alkoxycarbonyl or alkoxy radical, a halogen atom, a nitrile group or a haloalkyl group containing 1-12 carbon atoms, under the condition that if n equals 0, the radical R₁ denotes a linear or branched alkyl radical which may contain heteroatoms, which contain 1-12 carbon atoms, an aromatic or cycloaliphatic substituted or unsubstituted radical, which may contain heteroatoms, a carbonyl radical, an alkoxycarbonyl or alkoxy group, a halogen atom, a nitrile group or a haloalkyl group containing 1-12 carbon atoms.

EFFECT: method increases output and linearity of obtained products.
