Abstract

Synthetic, organic, polymeric membranes were prepared from polyacrylic acid salts for use with pervaporation apparatus in the separation of ehthanol-water mixtures. The polymeric material was prepared in dilute aqueous solution and coated onto a polysulfone support film, from which excess polymeric material was subsequently removed. Cross-links were then generated by limited exposure to toluene-2,4-diisocyanata solution, after which the prepared membrane was heat-cured. The resulting membrane structure showed selectivity in permeating water over a wide range of feed concentrations. 4 tabs.

Pervaporation separation of ethanol-water mixtures using polyethylenimine composite membranes

Patent Neidlinger, H.H.; Schissel, P.O.; Orth, R.A.

The method of separating which consists of an ethanol-water mixture through a membrane film, comprising: providing a polymeric membrane film having a first and second side and consisting essentially of ethylenimine polymers supported on a microporous member and having a partially cross-linked and heat-cured surface, the cross-linking having been achieved by the use of a cross-linking agent consisting essentially of an isocyanate compound; providing an ethanol-water feed solution on the first side of the membrane film; applying a pressure differential between the first and the second sides of the membrane film sufficient to induce a diffusion flow of a permeatemore »« less

Pervaporation properties of dense polyamide-6 membranes in separation of water-ethanol mixtures

Journal Article Kujawski, W.; Waczynski, M.; Lasota, M. [Nicolaus Copernicus Univ., Torun (Poland)] - Separation Science and Technology

Several dense polyamide-6 membranes were prepared by casting 7 wt% and/or 10 wt% solutions of polymer in trifluoroethanol. The cast membranes were dried at different temperatures from 25 to 80{degrees}C. Sorption and pervaporation properties of PA-6 membranes in water-ethanol mixtures were obtained. The data obtained showed that water was preferentially sorbed into the membrane and transported through the membrane; however, the pervaporation selectivity factor {alpha}{sup PV} was close to unity at higher concentrations. The selectivity parameters in pervaporation were improved for membranes obtained from 10 wt% polymer and dried at higher temperatures.
