Abstract
"PROCESSO DE CICLIZAçãO HIDROLìTICA". A presente invenção trata de um processo de ciclização hidrolítica de um composto de aminonitrila em lactama em presença de um catalisador. Ela trata mais particularmente de um processo de ciclização hidrolítica de um composto de aminonitrila em presença de um catalisador sólido de tipo argila. A presente invenção aplica-se em particular à preparação de <sym>-caprolactama por ciclização hidrolítica da aminocapronitrila.
