Abstract

The permeability and selectivity of nylon-6, cellophane, and cellulose 2.5-acetate membranes toward binary mixtures of aliphatic alcohols and water were studied at 60°C. Commercial membranes made of the above materials were used with and without preswelling. The cellophane membranes swelled considerably more than the other types of membranes in both water and in aqueous isopropanol mixtures containing over 40 mole% H2O. Therefore, the effects of swelling on membrane permeability were examined in some detail with cellophane membranes. The permeability characteristics of cellophane membranes could be altered significantly by suitable pretreatment. The effects of pretreatment are negligible in the case of cellulose 2.5-acetate and nylon-6 membranes.
