SUPPORTED LIQUID MEMBRANE CONTAINING ROOM TEMPERATURE IONIC LIQUID BLEND AND A PREVAPORATIVE-RECOVERY METHOD BASED ON THE SAME CAPABLE OF MINIMIZING THE LOSS OF AN EXTRACTION SOLVENT

摘要

PURPOSE: A supported liquid membrane containing room temperature ionic liquid blend and a prevaporative-recovery method based on the same are provided to improve the prevaporation performance of butanol.;CONSTITUTION: A supported liquid membrane includes room temperature ionic liquid(RTIL) blend. The RTIL blend is phosphonium/ammonium ion mixed liquid or phosphonium/oleyl alcohol mixed liquid. The supported liquid membrane is used for prevaporative-recovering butanol. A prevaporative-recovery method for organic materials uses an organic material-water solution as a supplying solution. The supported liquid membrane with the RTIL blend is mounted at a permeation cell. The organic material is butanol.;COPYRIGHT KIPO 2012
