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.

摘要： Disclosed is a method for the production of adipodinitrile by hydrocyanation of 1,3-butadiene on a catalyst, wherein in a first step 1,3-Butadiene is hydrocyanated to form 3-Pentene nitrile on at least one nickel(0) catalyst and, in a second step, 3-Pentene nitrile is hydrocyanated to form adipodinitrile on at least one nickel(0)-catalyst by adding at least one Lewis acid. At least one of the at least one nickel(0) catalysts used in the respective steps of the inventive method is converted in the other step.
