Abstract

"PROCESSO PARA SEPARAR MISTURAS AZEOTRóPICAS OU DE EBULIçãO PRóXIMA POR MEIO DE UMA RETIFICAçãO EXTRATIVA". Um método para separar misturas azeotrópicas ou de faixa de ebulição estreita por retificação extrativa, no qual líquido iónico é usado como um agente de arraste. O produto de fundo de ebulição alta é removido da coluna por um fluxo lateral em uma forma gasosa.
