Abstract

"PROCESSO PARA SEPARAçãO DE MISTURAS DE MATERIAIS TENDO PONTOS DE EBULIçãO DIFERENTES". A invenção refere-se a uma mistura de materiais tendo pontos de ebulição diferentes que é separada em frações tendo pontos de ebulição diferentes. A fração separada contendo o produto desejado é extraída usando os vapores de uma fração de ebulição inferior. O processo da presente invenção é particularmente útil para recuperar um isómero ou mistura de isómero desejado de uma mistura técnica obtida durante a produção de uma amina aromática tal como diamina de tolueno. Pouco ou nenhum isómero ou subproduto indesejado está presente no isómero ou produto de isómero ou de mistura de isómero desse processo.
