| titleOfInvention | Lewis acid recycling process |
| abstract | A process for the recovery of a Lewis acid from a reaction mixture (I) obtained by the hydrocyanation of an olefinically unsaturated compound to give a nitrile which has a miscibility gap with water under certain quantity, pressure and temperature conditions, in the presence of a catalyst system a Lewis acid and a complex compound of a phosphorus-containing compound suitable as a ligand and a central atom suitable for this compound, characterized in that one a) separating said complex compound from mixture (I) to obtain a mixture (II), b) Mixing (II) with water and converting it into pressure and temperature conditions such that a phase (III) which contains a higher proportion of water than said nitrile and a phase (IV) which contains a higher proportion contains said nitrile than water, phase (III) having a higher content of said Lewis acid than phase (IV), c) phase (III) with a liquid diluent (V), the c1) does not form an azeotrope with water and whose boiling point is higher than that of water or under certain pressure conditions c2) forms an azeotrope or heteroazeotrope with water under certain pressure conditions, d) the mixture of phase (III) and liquid diluent (V) is subjected to distillation under the pressure conditions mentioned in step c1) or c2) to obtain a mixture (VI) which ... |
