Abstract: A PROCESS FOR EXTRACTIVELY REMOVING NICKEL(0) COMPLEXES HAVING PHOSPHORUS LIGANDS AND/OR FREE PHOSPHORUS LIGANDS FROM A REACTION EFFLUENT OF A HYDROCYANATION OF UNSATURATED MONONITRILES TO DINITRILES BY EXTRACTION BY MEANS OF A HYDROCARBON, A PHASE SEPARATION OF THE HYDROCARBON AND OF THE REACTION EFFLUENT INTO TWO PHASE SBEING EFFECTED AT A TEMPERATURE T (IN °C), WHEREIN THE CONTENT OF NICKEL(0) COMPLEXES HAVING PHOSPHORUS LIGANDS AND/OR TREE PHOSPHORUS LIGANDS IN THE REACTION EFFLUENT OF THE HYDROCYANATION, DEPENDING ON THE TEMPERATURE T, IS AT LEAST Y% BY WEIGHT AND, IRRESPECTIVE OF THE TEMPERATURE T, IS A MAXIMUM OF 60% BY WEIGHT, WHERE THE NUMERICAL VALUE OF THE MINIMUM CONTENT Y IS GIVEN BY THE EQUATION Y = 0.5- T + 20 AND T IS TO BE USED IN THE EQUATION AS A DIMENSIONLESS NUMERICAL VALUE.
