Abstract: A process for dewatering hydrocyanic acid by distillation, which includes distilling crude hydrocyanic acid containing from 50 to 99.9% by weight of HCN, from 0.1 to 40% by weight of water, from 0 to 15% by weight of carbon oxides and optionally from 0.01 to 1% by weight of an involatile stabilizer, at a pressure of from 1 bar to 2.5 bar, a bottom temperature of from 100° C. to 130° C. and a top temperature of from 25° C. to 54° C., in the absence of a volatile stabilizer, in a distillation column to obtain a top draw stream containing purified, anhydrous hydrocyanic acid and carbon oxides and a bottom draw stream including water and, optionally, the involatile stabilizer.

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.
