Abstract

SEPARACION DE PENTAFLUOROETANO DE UNA MEZCLA DE PENTAFLUOROETANO Y CLOROPENTAFLUOROETANO, QUE CONSISTE EN: AGREGAR UN AGENTE EXTRACTIVO FLUOROCARBONADO DE 1 A 4 ATOMOS DE CARBONO, QUE CONTIENE OPCIONALMENTE HIDROGENO Y/O CLORO Y TIENE UN PUNTO DE EBULLICION > -39*C Y < 50*C, A LA PRIMERA MEZCLA PARA FORMAR UNA SEGUNDA MEZCLA RESULTANTE; SEPARAR EL PENTAFLUOROETANO DEL CLOROPENTAFLUOROETANO DE LA SEGUNDA MEZCLA POR DESTILACION EXTRATIVA Y CON ELLO RECUPERAR, COMO PRODUCTO DE CABEZAS, UNA CORRIENTE DE PENTAFLUOROETANO EXENTA DE CLOROPENTAFLUOROETANO.
