Abstract: 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.

Abstract: Preparation of nickel(0)-phosphorus ligand complexes (Q) containing at least a nickel(0) as central atom and at least a ligand containing phosphorus comprises reacting a nickel(II) compound with a reducing agent in the presence of the ligand to obtain a reaction mixture and extracting the obtained reaction mixture by adding at least a dinitrile, at least a hydrocarbon and at least two immiscible phases. Preparation of nickel(0)-phosphorus ligand complexes (Q) containing at least a nickel(0) as central atom and at least a ligand containing phosphorus comprises reacting a nickel(II) compound with a reducing agent in the presence of the ligand to obtain a reaction mixture, and extracting the obtained reaction mixture by adding at least a dinitrile, at least a hydrocarbon and at least two immiscible phases, where: the amount of nickel(0) content in the reaction mixture is at most 1.3 wt.%; the molar ratio of: the reducing agent to the nickel(II) compound is 1:1-1000:1, which is calculated as the molar ratio of the redox equivalent, and the ligand containing phosphorus to the nickel(II) compound is at most 30:1, which is calculated as the molar ratio of phosphorus and nickel atoms. Independent claims are included for: (1) a mixture comprising (Q), obtained by the above process; and (2) a method for the isomerization of unsaturated nitrile to linear unsaturated nitrile using (Q) as catalyst, which is regenerated by circulation method.
