摘要：
The invention relates to a method for the extractive separation of nickel(0) complexes and phosphorus-containing ligands and/or free phosphorus-containing ligands from a reaction discharge of a hydrocyanation of unsaturated mononitries to dinitriles, by means of a hydrocarbon, the hydrocarbon and the reaction discharge being separated into two phases at a temperature T (in °C). The invention is characterised in that the content of nickel(0) complexes and phosphorus-containing ligands and/or free phosphorus-containing ligands in the reaction discharge of the hydrocyanation is at least y wt. %, depending on the temperature T, and a maximum of 60 wt. % independently of the temperature T. The numerical value of the minimum content y is indicated by the equation y = 0,5 T + 20, T being a dimensionless numerical value.
