Abstract: A method for producing ε-caprolactam and a method for reactivating a zeolite catalyst for the production are provided. In the reactivation step, a zeolite catalyst is allowed to contact a gas containing a carboxylic acid, water and a compound selected from ammonia and amines. In accordance with the present invention, the catalytic activities of a zeolite catalyst used for the Beckmann rearrangement reaction of cyclohexanone oxime can be effectively restored. Consequently, ε-caprolactam may be produced with a high production yield for a long period of time by reusing the catalyst by the method described above.

Abstract: An improved process for the preparation of a lactam-magnesium compound which involves bringing into intimate admixture a lactam monomer represented by the following structural formula: ##STR1## wherein Y is an alkylene group having from 3 to 12 carbon atoms, in particulate form, and an organomagnesium-containing material. The process is carried out at a temperature below the melting point of the lactam monomer but at a temperature sufficient to convert at least a portion of the lactam monomer to said lactam-magnesium compound in pulverulent form. The lactam-magnesium compound is useful as a catalyst for anionic lactam polymerization.
