    Abstract: The invention relates to a method for removing water from a mixture containi ng water and zinc chloride. The invention is characterized in that said mixture containing water and zinc chloride is mixed with an aprotic, polar diluting agent whose boiling point, in the event of non-azeotropic formation of said diluting agent with water under the pressure conditions of the distillation mentioned below, is higher than the boiling point of water and is liquid at the boiling point of water or one azeotrope or heteroazeotrope with water is formed under the pressure and temperature conditions of the distillation mentioned below, and the mixture containing water, zinc chloride and the diluting agent is distilled while removing water or said azeotrope or said heteroazeotrope from this mixture while obtaining a water-free mixture containing zinc chloride and said diluting agent.

    Abstract: The invention relates to a method for the recycling of a Lewis acid from a reaction mixture (I), obtained from the hydrocyanation of an olefinically- unsaturated compound to give a nitrile, which has a miscibility gap with wat er under certain concentration, pressure and temperature conditions, in the presence of a catalyst system comprising a Lewis acid and a complex compound of a phosphorus-containing compound suitable as a ligand and a central atom suitable for said compound, characterised in that a) said complex compound i s separated from a mixture (I) to give a mixture (II), b) mixture (II) is treated with water and undergoes a transformation generating pressure and temperature conditions to give a phase (III) with a higher proportion of wat er than said nitrile and a phase (IV) which has a higher proportion of said nitrile than of water, whereby phase (III) has a higher content of said Lewi s acid than phase (IV), c) phase (III) is treated with a liquid diluent (V) which c1) does not form an azeotrope with water and the boiling point of whi ch is higher than that of water under certain pressure conditions, or c2) forms an azeotrope or heteroazeotrope with water under certain pressure conditions , d) the mixture of phase (III) and liquid diluent (V) is distilled under the pressure conditions given in step c1) or c2) to give a mixture (VI) which ha s a higher proportion of water than of liquid diluent (V) and a mixture (VII) which has a higher proportion of diluent (V) than water, whereby mixture (VI I) has a higher content of said Lewis acid than mixture (VI), and e) mixture (VII) is fed to a hydrocyanation of an olefinically-unsaturated compound to give a nitrile, which has a miscibility gap with water under certain concentration, pressure and temperature conditions, in the presence of a catalyst system comprising a Lewis acid and a complex compound of a phosphor us- containing compound suitable as a ligand and a central atom suitable for sai d compound.
