The separation of an ethanol-water solution by steady-state pervaporation was investigated. Poly(acrylonitrile-co-acrylic acid) was prepared and used as a membrane. The permeate flux and separation factor were measured over the full range of ethanol-water composition at temperatures 30, 40 and 50 o C. Pervaporation exhibited negative deviations from ideal pervaporation behavior and the separation...
