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 phases being effected at a temperature T (in ° C.), wherein the content of nickel(0) complexes having phosphorus ligands and/or free 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.

Abstract: Procedimiento para la separación por destilación de isómeros de pentenonitrilo, que presentan en el intervalo de presión de 1 a 500 kPa una volatilidad relativa alfa en el intervalo de 1, 0 a 1, 3, caracterizado porque la destilación se lleva a cabo en presencia de un diluyente líquido, que, bajo las mismas condiciones de presión, forma azeótropos con los isómeros de pentenonitrilo, cuya volatilidad relativa alfa es más elevada que la de los isómeros de pentenonitrilo a separar.
