Abstract: Process for the preparation of a 2-pyrrolidone by hydrogenation of optionally substituted succinonitrile in the liquid phase in the presence of ammonia using a fixed-bed catalyst and treatment of the hydrogenated product with water, in which the hydrogenation one or more times is interrupted for regenration of the catalyst by passing liquid ammonia at 75-130°C, subsequently hydrogen at 1 30 -350°C and then liquid ammonia again at 75-130°C over the catalyst.

Abstract: The invention relates to a process for the synthesis of ε-caprolactam, the process comprising:
(A) heating a salt of L-lysine in a solvent comprising an alcohol, at a temperature of about 99°C to about 201 °C, to produce α-amino-ε-caprolactam; and
(B) deaminating α-amino-ε-caprolactam produced in (A) by a method comprising contacting it at least once with a deamination catalyst at a temperature below the freezing point of water, to produce ε-caprolactam.

Abstract: The invention relates to a method for separating high boilers out from a crude caprolactam, which contains high boilers, caprolactam and, optionally, light boilers, and which has been obtained by: a) reacting 6-aminocapronitrile with water to form a reaction mixture, and; b) separating ammonia and unreacted water out from the reaction mixture while obtaining a crude caprolactam. The invention is characterized in that: c) the crude caprolactam is fed to a distillation device while obtaining, as a product, a first partial flow via the top, and obtaining a second partial flow via the bottom. During distillation, the pressure is set so that a bottom temperature of 170 °C is not fallen below, and the second partial flow is set so that the caprolactam content of the second partial flow is no less than 10 % by weight with regard to the entire second partial flow.

Abstract: The invention relates to a method for producing caprolactam, characterized in that a) a mixture (I) containing 6-aminocapronitrile and water in the liquid phase is converted into a mixture (II) containing caprolactam, ammonia, water, high boilers and low boilers in the presence of a catalyst; b) ammonia is then removed from mixture (II), leaving a mixture (III) containing caprolactam, water, high boilers and low boilers; c) water is then removed from mixture (III) leaving a mixture (IV) containing caprolactam, high boilers and low boilers, and d) a solid (V) containing caprolactam is obtained from mixture (IV) by crystallization, the proportion by weight of caprolactam in the solid (V) being greater than that in the mixture (IV).
