Abstract

"PROCESSO DE PURIFICAçãO DE LACTAMAS E INSTALAçãO PARA A REALIZAçãO DE UM PROCESSO DE PURIFICAçãO DE LACTAMAS". A presente invenção trata de um processo de purificação de lactamas, mais particularmente de lactamas obtidas por hidrólise ciclizante de uma aminonitrila. A presente invenção trata mais particularmente da purificação de uma <sym>-caprolactama obtida por hidrólise ciclizante da aminocapronitrila que consiste em eliminar a amónia do meio reacional de hidrólise, e depois em recuperar a lactama do referido meio em forma purificada. Essa recuperação é efetuada realizando-se pelo menos uma destilação da lactama em presença de uma base que produz eventualmente uma fração de topo que compreende compostos mais voláteis que a lactama, uma fração que compreende a lactama a ser recuperada no grau de pureza desejada e um produto de fundo de destilação que compreende lactama e compostos menos voláteis que a lactama. O fundo de destilação é tratado com diferentes processos como a evaporação em camadas finas para recuperar a maior parte da caprolactama contida e sua reciclagem no processo de recuperação. A presente invenção permite uma taxa de recuperação elevada da caprolactama contida no meio de hidrólise, respeitando ao mesmo tempo os critérios de pureza exigidos.
