Overview: The separation of alcohol-water mixtures by pervaporation has been preferentially carried out through hydrophobic membranes because it is more practical to permeate alcohol through the membrane. Nevertheless, most polymeric membranes are water permselective as the molecular size of water is smaller than that of ethanol. Ethanol-permselective membranes have been limited to silicon- and fluorine-containing polymers, for example, polydimethylsiloxane (PDMS), poly (1-trimethylsilyl-1-propyne) (PTMSP) and poly (tetrafluoroethylene) derivatives. PTMSP is known to show preferential permeation of ethanol in the pervaporation of ethanol-water mixtures.
