Abstract
Pervaporation of 1-butanol and isopropyl alcohol (IPA) through a poly vinyl chloride membrane (PVC) as the active layer and a porous hydrophobic polyvinyldene fluoride membrane as the support layer was conducted by dissolving ionic liquids, such as Aliquat 336, Cyphos 101, 102 and 104 in PVC. The effects of the ionic liquids, membrane thickness and feed concentration on the permeation flux, selectivity and separation factor at room temperature were examined and it was found that the membrane with the ratio of Aliquat 336/PVC=70/30 (w/w) gave the highest permeability and separation factor.
