Abstract

Patente de Invenção: "PROCESSO DE SEPARAçãO DE CARBONATO DE DIMETILA E METANOL". Esta invenção refere-se a um processo para a separação de metanol e de carbonato de dimetila em uma coluna de destilação através de destilação extrativa. A destilação extrativa é conduzida na presença de um agente de destilação extrativa que modifica o comportamento azeotrópico da mistura de carbonato de dimetila/metanol. Uma corrente lateral de vapor é removida da coluna de destilação.
