| titleOfInvention | Preparation of caprolactam |
| abstract | A process for the preparation of caprolactam, wherein (a) a mixture (I) containing 6-aminocapronitrile and water is caused to react in the vapor phase in the presence of a catalyst to form a mixture (II) containing caprolactam, ammonia, water, high boilers and low boilers, after which (b) ammonia is removed from mixture (II) to give a mixture (III) containing caprolactam, water, high boilers and low boilers, after which (c) water is removed from mixture (III) to give a mixture (IV) containing caprolactam, high boilers and low boilers, and then (d) a caprolactam-containing solid (V) is obtained from mixture (IV) by recrystallization, the percentage by weight of caprolactam in solid (V) being greater than in mixture (IV). |
