Abstract

Abstract Translated from German Verfahren zur Gewinnung von Caprolactam durch Spaltung von Oligomeren des Caprolactams, wobei man die Oligomeren bei erhöhter Temperatur durch eine katalytische Schicht von Aluminiumoxid leitet, wobei man die Oligomeren flüssig oder in festem Zustand in eine Aluminiumoxidwirbelschicht einbringt und unter Mitverwendung von Wasserdampf bei einer Temperatur von 290 bis 400 °C spaltet. Process for the production of caprolactam by cleavage of oligomers of caprolactam, the oligomers being passed at elevated temperature through a catalytic layer of aluminum oxide, the oligomers being introduced into an alumina fluidized bed in liquid or solid state and with the use of water vapor at a temperature of 290 splits up to 400 ° C.
