Abstract

OBJETO SE DISPONE UN PROCEDIMIENTO DE SEPARACION DE FORMA EFECTIVA DE PENTAFLUOROETANO (HFC-125) DE UNA MEZCLA DE HFC Y CLOROPENTAFLUOROETANO (CFC-115). CONSTITUCION CUANDO LA MEZCLA DE HFC-125 Y CFC-115 ES SOMETIDA A DESTILACION EXTRACTIVA PARA OBTENER HFC-125 CONCENTRADO, METANOL, ETANOL, BUTANOL, ALCOHOL PROPILICO, PENTAFLUOPROPANOL, TETRAFLUOPROPANOL O ACETONA SE USA COMO UN EXTRACTO, POR LO QUE SE OBTIENE CFC-115 COMO UN PRODUCTO DESTILADO Y SE OBTIENE UNA MEZCLA DE HFC-125 Y EL EXTRACTO COMO UN PRODUCTO FINAL. A CONTINUACION, EL EXTRACTO SE SEPARA DE HFC-125 MEDIANTE DESTILACION DE LA MEZCLA Y SE REUTILIZA EN LA DESTILACION EXTRACTIVA.
