Abstract: Elle concerne plus particulièrement un procédé de préparation de cyclohexanone présentant une teneur en impuretés permettant une utilisation de la cyclohexanone comme matière première pour la fabrication d'ε-caprolactame.Le procédé de l'invention comprend notamment un traitement du mélange cyclohexanol/cyclohexanone issu de l'oxydation par l'oxygène du cyclohexane dans une étape de déshydrogénation pour transformer le cyclohexanol en cyclohexanone et les impuretés présentes telles que le cyclopentènal. Le procédé de l'invention permet d'obtenir une cyclohexanone présentant un degré de pureté élevé, compatible pour son utilisation comme matière première dans la synthèse de l'ε-caprolactame.

Abstract: The present invention relates to a process for the manufacture of dinitrile compounds by double hydrocyanation of an olefin. It relates particularly to a process for the manufacture of dinitrile compounds by double hydrocyanation of an olefin present in a mixture of hydrocarbons, such as a petroleum fraction and more particularly still a petroleum fraction known under the name of C4 fraction. The process of the invention comprises a sequence of stages for the separation of the various compounds which makes it possible to remove the byproducts, such as the products from the trimerization of alkynes, present in the C4 fraction and thus to prevent their accumulation in the hydrocyanation reactors.

Abstract: The present invention relates to a process for the manufacture of lactams. It relates more particularly to a process for the manufacture of lactams from alkyl cyanovalerate compounds obtained by using, as starting materials, in particular unsaturated mononitrile compounds and more particularly pentenenitriles, such as 2-, 3- or 4-pentenenitrile, taken in isolation or as a mixture, and referred to below as PN for the mixture and 2PN, 3PN and 4PN respectively. This process consists in carrying out the hydrogenation and the cyclization of the alkyl cyanovalerate to give s-caprolactam without intermediate separation of the alkyl aminocaproate.
