摘要： The invention relates to a method for dehydrating hydrocyanic acid by distillation. Said method is characterised in that a crude hydrocyanic acid containing between 50 and 99.9 wt. % HCN, between 0.1 and 40 wt. % water, between 0 and 15 wt. % carbon oxides and optionally between 0.01 and 1 wt. % non-volatile stabiliser is distilled in a distillation column at a pressure of between 1 bar and 2.5 bar, a sump temperature of between 100 °C and 130 °C and a head temperature of between 25 °C and 54 °C in the absence of a volatile stabiliser. A discharge stream, containing purified anhydrous hydrocyanic acid and carbon oxides is thus obtained from the head and a discharge stream containing water and optionally the non-volatile stabiliser is obtained from the sump.

摘要： The invention relates to a method for removing, by distillation, 6-aminocapronitrile from mixtures that contain 6-aminocapronitrile, adipodinitrile and hexamethylenediamine, by a) removing the hexamethylenediamine from the mixture while obtaining a mixture (I) that has a hexamethylenediamine content of less than 1 wt.- %, b) removing completely or partially the 6-aminocapronitrile from mixture (I) while obtaining a mixture (II) whose content in substances that have a higher boiling point as 6-aminocapronitrile under distillation conditions and that cannot be formed by dimerization reactions when 6-aminocapronitrile is thermally treated is less than 1 wt.- %, and c) completely or partially removing from mixture (II) the hexamethylenediamine that might be present while obtaining a mixture (IV) whose hexamethylenediamine content is higher than that of mixture (II), and a mixture (V) whose hexamethylenediamine content is lower than that of mixture (II).

摘要： The invention relates to a method for regenerating a heterogeneous catalyst, which is used with hydrogen, in order to produce compounds containing NH2 groups by hydrogenating compounds that contain at least one unsaturated carbon-nitrogen bond. The inventive method is characterized in that: a) the supply of the compound to be hydrogenated is stopped, and; b) the heterogeneous catalyst or mixtures thereof is/are treated with a compound of formula (I) R?1R2N-CO-R3¿, whereby R1 represents hydrogen and C¿1?-C4 alkyl, R?2 and R3¿, independent of one another, represent hydrogen and C¿1?-C4 alkyl or, together, represent a C3-C6 alkylene group, under a pressure ranging from 0.1 to 30 MPa and at a temperature ranging from 100 to 300 °C. The heterogeneous catalyst is treated with said compound of formula (I) provided that this compound is liquid during the treatment.

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).
