Abstract

"PROCESSO PARA SEPARAçãO POR DESTILAçãO DE PARTE DE OU TODA UMA IMINA". A invenção é relacionada a um processo para separar por destilação toda ou parte de uma imina (III) de uma mistura (II) contendo uma amina (I) e uma imina (III). Dito processo é caracterizado em que um composto (IV) que sob as condições da destilação é inerte em relação a amina (I) e cujo ponto de ebulição sob as condições da destilação situa-se acima do ponto de ebulição da amina, é adicionado a mistura de destilação, e que a destilação rende uma mistura (VI) a qual essencialmente contém um composto (IV).
