Abstract: A new kind of membrane was prepared by blending 5 wt% poly(1-vinylpyrrolidone-co-acrylic acid) with cellulose acetate propionate for the separation of ethyl tert-butyl ether and ethanol mixtures. The membrane properties were evaluated by pervaporation and sorption of mixtures of ethyl tert-butyl ether/ethanol. The experimental results show that the selectivity and the fluxes of this membrane depend upon the feed composition and upon the temperature. The minimum values of ethanol concentration in the permeate and in the sorption solution were obtained in the vicinity of the azeotropic point. Compared with the pure CAP membrane, the new membrane shows high performance for the separation of ETBE and EtOH mixtures, especially under high temperature conditions. [ABSTRACT FROM AUTHOR]
