Method for preparing lactam |
| abstract |
The present invention consists of a process for preparing lactam by vapor phase reaction of an aliphatic aminonitrile with water, in the presence of a solid catalyst, characterized in that the catalyst is an alumina having a specific surface measured by the BET method greater than or equal to 10 m2 / g. Aliphatic lactams, such as in particular epsilon-caprolactam, are compounds base for the preparation of polyamides (polyamide 6 from caprolactam). |
