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: Producing 3-pentenonitrile comprises isomerizing a 2-methyl-3-butenonitrile feed stream in the presence of a dissolved or dispersed catalyst, distilling the product stream to separate an overhead stream (2) from a catalyst-containing bottoms stream, distilling stream (2) to obtain an overhead stream enriched in (Z)-2-methyl-2-butenonitrile and a bottoms stream (5), and distilling stream (5) to produce a bottoms stream containing 3-pentenonitrile and an overhead stream containing 2-methyl-3-butenonitrile.

Abstract: A process for the removal of water from a mixture comprising water and zinc chloride, which comprises adding to said mixture comprising water and zinc chloride an aprotic, polar diluent whose boiling point in the case where an azeotrope is not formed between said diluent and water under the pressure conditions of the distillation mentioned below is higher than the boiling point of water and which is in liquid form at this boiling point of water or which forms an azeotrope or heteroazeotrope with water under the pressure and temperature conditions of the distillation mentioned below, and distilling the mixture comprising water, zinc chloride and the diluent with removal of water or said azeotrope or said heteroazeotrope from this mixture, giving an anhydrous mixture comprising zinc chloride and said diluent.

Abstract: Hydrocyanation of olefinically unsaturated nitriles in the presence of a zero-valent nickel catalyst comprises performing the reaction in the presence of a hydrocarbon that forms a catalyst-rich phase and a catalyst-lean phase. An independent claim is also included for separating adiponitrile from a mixture comprising adiponitrile and a zero-valent nickel catalyst by means of a hydrocarbon with a b. pt. of 90-140[deg]C.
