Specialty Polymeric Membranes .2. Pervaporation Separation of Aqueous Lower Alcohol-Solutions Through Modified Polybutadiene Membranes
Uncrosslinked and crosslinked polybutadiene membranes were used to investigate the pervaporation of lower alcohol/water mixtures (alcohol : methanol, ethanol, 1-propanol, 2-propanol, and t-butanol). Crosslinked polybutadiene membrane permeated lower alcohols in preference to water indicating that polybutadiene must be a candidate for permselective membranes for alcohol/water mixtures.
