SEPARATING FILM OF A WATER-ETHANOL MIXTURE AND A METHOD FOR FABRICATING THE SAME CAPABLE OF FABRICATING FUEL GRADE ETHANOL BY ELIMINATING WATER FROM THE WATER-ETHANOL MIXTURE

摘要

PURPOSE: The separating film of a water-ethanol mixture and a method for fabricating the same are provided to eliminate water from the water-ethanol mixture based on the superior selectivity and transmittance. ;CONSTITUTION: The separating film of a water-ethanol mixture includes the 5:5 ratios of polyvinyl alcol99 and polyvinyl alcohol88. A cross-linking agent for the separating film includes glutaraldehyde and polyallylamine hydrochloride. The amount of the glutaraldehyde is between 0.2 and 0.3 weight%. An inorganic material is additionally included in the separating film and is based on TiO_2 particles or TiO_2 paste.;COPYRIGHT KIPO 2011
