Abstract

"PROCESSOS PARA TRATAMENTO DE UM MEIO LìQUIDO CONTENDO PELO MENOS UMA LACTAMA E PARA PURIFICAçãO DE LACTAMAS OBTIDAS POR HIDRóLISE CICLIZADORA DE UMA AMINONITRILA". A presente invenção refere-se a um processo de tratamento de lactamas. Este processo permite, principalmente, modificar a natureza química das impurezas contidas em um meio contendo lactamas ou para transformar as mesmas em compostos não prejudiciais ou em compostos extraíveis em operações de purificação ulteriores. Ele consiste em realizar uma hidrogenação, na presença de amoníaco, do meio contendo a lactama.
