Abstract: Process for preparing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphorous ester diamides, aminophosphines, diaminophosphines, phosphorous ester amide halides and aminophosphine halides with elimination of an acid in the presence of an auxiliary base, wherein the auxiliary base b) and the acid form a salt which is liquid at temperatures at which the desired product is not significantly decomposed during the process of separating off the liquid salt and c) the salt of the auxiliary base forms two immiscible liquid phases with the desired product or the solution of the desired product in a suitable solvent.

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.
