Abstract: A system suitable for use as a catalyst for the hydrocyanation of olefinical ly unsaturated compounds, containing a) Ni(0), b) Ni(0) as a ligand complex- fixing compound containing trivalent phosphorus, c) a Lewis acid and d) a compound of formula MRn wherein M = AI or Ti, R= identical or different monovalent alkoxyl radicals, wherein several alkoxy radicals can be interbridged, also in the case where M = AI, R = identical or different alky l radicals wherein several alkyl radicals can be interbridged or one or severa l alkyl radicals can be bridged by one or several of the above-mentioned alkox y radicals, n = valency of M. The invention also relates to methods for the hydrocyanation of an olefinically unsaturationed compound in the presence of said system.

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.
