ABSTRACT:
Ethylenically unsaturated aliphatic nitriles, for example the linear pentenenitriles, are converted/hydrocyanated into their corresponding dinitriles, for example adiponitrile, by reacting such nitriles with hydrogen cyanide, in an aqueous reaction medium which comprises (1) a catalytically effective amount of a transition metal compound and a sulfonated phosphine, together with (2) a cocatalytically effective amount of at least one Lewis acid; the Lewis acid cocatalyst promotes the linearity of the final product dinitriles and/or prolongs the useful life of the catalyst.
