    摘要: The invention concerns a method for hydrocyanation of ethylenically unsaturated organic compounds comprising at least a nitrile function. The invention provides a method for hydrocyanation of an ethylenically unsaturated hydrocarbon compound by reacting in liquid medium the hydrogen cyanide in the presence of a catalyst comprising a metal element selected among transition metals and an organophosphorous ligand, characterised in that the organophosphorous ligand is a furylphosphine. The invention is in particular useful for synthesizing adiponitrile from butadiene.

    摘要: The present invention relates to the manufacture of nitrile compounds from unsaturated organic compounds by reaction with hydrogen cyanide. It relates more particularly to the manufacture of nitrile compounds of use in the synthesis of adiponitrile, an important chemical intermediate in the manufacture of major chemical compounds, such as hexamethylenediamine and ε-caprolactam. The invention provides a process for the manufacture of organic compounds comprising at least one nitrile functional group by carrying out a hydrocyanation reaction between hydrogen cyanide and an organic compound comprising at least one ethylenic unsaturation. This reaction is carried out in the presence of a catalytic system comprising a metal element chosen from the group consisting of nickel, platinum and palladium and an organophosphorus ligand, the reaction medium additionally comprising an ionic liquid in the liquid state at least at the temperature at which the hydrocyanation reaction is carried out.
