Abstract

"PROCESSO DE SEPARAçãO POR DESTILAçãO DE AMONìACO CONTIDO EM UMA SOLUçãO AQUOSA DE CAPROLACTAMA". A presente invenção refere-se a um processo aperfeiçoado de destilação de amoníaco a partir de uma mistura, mais particularmente uma mistura proveniente da reação entre uma aminonitrila e água (reação também chamada de hidrólise ciclizante). Mais precisamente, a invenção consiste em um processo de destilação de amoníaco contido em uma solução aquosa de caprolactama, caracterizada em que se destila com a ajuda de uma coluna, com uma temperatura de base inferior ou igual a 160<198>C e sob uma pressão absoluta inferior ou igual a 5 bares, o amoníaco destilado no topo da coluna sendo comprimido sob uma pressão superior ou igual a 10 bares, depois condensado a uma temperatura de 25<198>C a 60<198>C.
