Abstract

"PROCESSO DE HIDRóLISE CICLIZANTE DE UM COMPOSTO AMINONITRILA EM LACTAMA POR REAçãO DE UMA AMINONITRILA". A invenção refere-se a um processo de hidrólise ciclizante de um composto aminonitrila em lactama em presença de um catalisador. Ela se refere mais particularmente a um processo de hidrólise ciclizante de um composto aminonitrila em presença de um catalisador em partículas macroporoso obtido por depósito/ impregnação de um composto oxigenado sobre um suporte macroporoso como alumina. A invenção se aplica notadamente à preparação de <sym> - caprolactama por hidrólise ciclizante de aminocapronitrila.
