Abstract
"SEPARAçãO DE éPSILON CAPROLACTAMO DE ISÈMEROS" Esta invenção se refere a um processo para a separação de épsilon caprolactamo de uma mistura de alimentação compreendendo épsilon caprolactamo e um ou mais isómeros de épsilon caprolactamo, selecionados no grupo que consiste em 4-etil-2-pirrolidinona, 5-metil-2-piperidinona, 3-etil-2-pirrolidinona e 3-metil-2-piperidinona, ou octaidrofenazina, compreendendo o contato, sob condições de adsorção, da mistura com um adsorvente, a adsorção seletiva dos isómeros de épsilon caprolactamo ou octaidrofenazina, excluindo-se substancialmente o épsilon caprolactamo, a remoção da parte não adsorvida da mistura de alimentação do contato com o adsorvente e, depois disso, a recuperação de épsilon caprolactamo de elevada pureza. Os isómeros de épsilon caprolactamo ou octaidrofenazina podem ser recuperados por dessorção sob condições de dessorção. O processo pode ser conduzido por bateladas ou semi-bateladas, ou de maneira contínua, usando-se tecnologias de leito móvel ou de leito móvel simulado.
