Abstract (en)
[origin: WO2007115936A2] The invention relates to a method for extractive separation of nickel (0) complexes with phosphorous ligands, from a reaction product of a hydrocyanation of unsaturated mononitriles to give dinitriles, by means of extraction with a hydrocarbon, wherein a phase separation of the hydrocarbon and the nitrile-containing solution into two phases occurs, by addition of a polar additive to the reaction product (feed stream) and/or the extraction stage.
