Abstract: The invention relates to a method for producing caprolactam, characterized in that a) a mixture (I) containing 6-aminocapronitrile and water in the liquid phase is converted into a mixture (II) containing caprolactam, ammonia, water, high boilers and low boilers in the presence of a catalyst; b) ammonia is then removed from mixture (II), leaving a mixture (III) containing caprolactam, water, high boilers and low boilers; c) water is then removed from mixture (III) leaving a mixture (IV) containing caprolactam, high boilers and low boilers, and d) a solid (V) containing caprolactam is obtained from mixture (IV) by crystallization, the proportion by weight of caprolactam in the solid (V) being greater than that in the mixture (IV).
