WERKWIJZE VOOR HET HYDROCYANEREN VAN ONVERZADIGDE ORGANISCHE VERBINDINGEN, MET TEN MINSTE EEN DUBBELE BINDING.

摘要

A process of hydrocyanation of unsaturated organic compounds, which contain at least one ethylenic double bond, comprising reacting these compounds with hydrogen cyanide in the presence of an aqueous solution of a sulfonated triarylphosphine compound preferably a water soluble salt of a mono- di- or trisulfonated triphenylphosphine which contains a transition metal compound, preferably a nickel compound. When the reaction is completed the resulting hydrocyanated compound and the catalytic solution can easily be separated and the latter be reused.
