Abstract: Extractive separation of nickel(0) complexes and phosphorus-containing ligands and/or free phosphorus-containing ligands (I) from a reaction discharge of a hydrocyanation of unsaturated mononitriles to dinitriles, through extraction by means of a hydrocarbon, where the hydrocarbon and the reaction discharge are separated into two phases. Extractive separation of nickel(0) complexes and phosphorus-containing ligands and/or free phosphorus-containing ligands (I) from a reaction discharge of a hydrocyanation of unsaturated mononitriles to dinitriles, through extraction by means of a hydrocarbon, the hydrocarbon and the reaction discharge being separated into two phases at a temperature T (in [deg]C); where the content of nickel(0) complexes and ligands in the reaction discharge of the hydrocyanation is at least y wt.%, depending on (T), and a maximum of 60 wt.% independently of (T). The numerical value of the minimum content y is indicated by the equation (y = 0.5T+20), where T being a dimensionless numerical value.

Abstract: The invention relates to a method for the isomerisation of pentenenitrile in an educt flow. Said isomerisation is carried out on a heterogeneous catalyst in a distillation column, such that during the isomerisation, the isomerisation educt is enriched by distillation in relation to the isomerisation product in the reaction column of the distillation column.
