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.

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: A process is described for preparing nickel(0)-phosphorus ligand complexes containing at least one nickel(0) central atom and at least one phosphorus ligand. The process comprises reducing a nickel(II) source comprising nickel bromide, nickel iodide or mixtures thereof in the presence of at least one phosphorus ligand.
