Abstract
The present invention relates to a process for the preparation of lauryllactam in which a Beckmann rearrangement of cyclododecanone oxime is carried out. Said process is carried out in the gas phase at a temperature of between 180 and 450° C. in the presence of a microporous material having a three-dimensional inorganic main structure composed of tetrahedra connected via a common edge, called zeolite.
