A method for the hydrocyanation of ethylenically nitrile-unsaturated organic compounds, and particularly diolefins or substituted olefins such as alkene nitriles. Specifically, the method is for hydrocyanating organic compounds comprising at least one double ethylene bond by reacting them with hydrogen cyanide in the presence of an aqueous solution of a catalyst that includes at least one transition metal compound and at least one water-soluble phosphine, wherein said water-soluble phosphine is a monodentate or bidentate phosphine.
La présente invention concerne un procédé d'hydrocyanation de composés organiques à insaturation éthylénique en nitriles, notamment l'hydrocyanation des dioléfines ou des oléfines substituées telles que des alcène-nitriles. Plus précisément, elle consiste en un procédé d'hydrocyanation de composés organiques comportant au moins une double liaison éthylénique par réaction avec le cyanure d'hydrogène, en présence d'une solution aqueuse d'un catalyseur comprenant au moins un composé d'un métal de transition et au moins une phosphine hydrosoluble, caractérisé en ce que ladite phosphine hydrosoluble est une phosphine monodentate ou bidentate.
