Abstract
(DE)
Herstellung von Cyclohexanonoxim durch Umsetzung von Cyclohexanon mit einem Hydroxylammoniumsalz, indem man als Hydroxylammoniumsalz Hydroxylammoniumformiat einsetzt, sowie Herstellung von Caprolactam durch Beckmann-Umlagerung von Cyclohexanonoxim in einer C1-C4-Carbonsäure.
(EN)
The production of cyclohexanonoxim by the reaction of cyclohexanone with a hydroxyl ammonium salt, i.e. hydroxyl ammonium formiate, and the production of caprolactam by the Beckmann rearrangement of cyclohexanonoxim in a C1-C4 carboxylic acid.
(FR)
L'invention concerne la production de cyclohexanonoxime par réaction de cyclohexanone avec un sel d'hydroxylammonium, à savoir du formiate d'hydroxylammonium, ainsi que la production de caprolactame par la transposition de Beckmann de cyclohexanonoxime dans de l'acide carboxylique C1-C4.
