摘要： The invention relates to a method for removing water from a mixture containing 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.

摘要： The invention relates to a method for purifying crude caprolactam that has been obtained by: 1) reacting a mixture (I) containing 6-aminocapronitrile and water to form a mixture (II) containing caprolactam, ammonia, water, high boilers and low boilers in the presence of a catalyst followed by; 2) removing ammonia from mixture (II) while obtaining a mixture (III) that contains caprolactam, water, high boilers and low boilers, after which; 3) water is entirely or partially removed from mixture (III) while obtaining a crude caprolactam (IV) that contains caprolactam, high boilers and low boilers. The inventive method is characterized in that: a) the crude caprolactam and an inorganic acid, which has a boiling point higher that that of caprolactam under distillation conditions in accordance with subsequent steps b) to h), are fed to a first distillation device K1; b) the crude caprolactam and the inorganic acid are distilled in the first distillation device K1 during which a first partial flow in the bottom area and a second partial flow in the top area are withdrawn from the distillation device K1; c) the second partial flow from step b) is fed to a second distillation device K2; d) the second partial flow from step b) is distilled in the second distillation device K2 during which a first partial flow in the bottom area and a second partial flow in the top area are withdrawn from the distillation device K2; e) a first partial flow from step d) is fed to a third distillation device K3; f) the first partial flow from step d) is distilled in the third distillation device K3 during which a first partial flow in the bottom area and purified caprolactam in the top area are withdrawn from the distillation device K3, and; g) the first partial flow from step f) is fed to the first distillation device K1.

摘要： The invention relates to a method for separating ammoniac (I) from mixtures (II) containing ammoniac (I) and an amide (IV) is obtained by reacting educts (III) selected from the group consisting of nitriles (IIIa), amines (IIIb), aminonitriles (IIIc) and aminoamides (IIId) with water. The method is characterised in that a) the educt (III) is reacted with water in liquid phase in the presence of an organic liquid diluting agent (V) to form a mixture (II) containing amide (IV) and ammoniac (I), b) the mixture (II) is transformed under conditions of mass, pressure and temperature - under which the diluting agent (V) and the water are in a liquid state and exhibit a miscibility gap - in order to obtain a two phase system consisting of a phase (VII), c) phase (VII) is separated from phase (VIII), d) the ammoniac present in phase (VII) is separated by extraction (a) by means of a mixture (IX) containing water in order to obtain a mixture (XI) which contains less ammoniac than phase (VII), and e) the diluting agent (V) is separated from the mixture (XI) in order to obtain the amide (IV).

摘要： The invention concerns a process for simultaneously preparing 6-aminocapronitrile and hexamethylene diamine proceeding from adipodinitrile. The process is characterized in that: (1) adipodinitrile is partially hydrogenated in the presence of a catalyst in order to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine and adipodinitrile; (2) 6-aminocapronitrile and hexamethylene diamine are separated from the mixture; (3) between 0.01 and 10 wt %, relative to adipodinitrile, of an acid or an acidic ion exchanger is added to the part substantially containing adipodinitrile, and the adipodinitrile is separated from the mixture; and (4) the adipodinitrile is returned to step (1).
