抄録
Separation of water-ethanol mixtures through asymmetric polyimide membranes prepared by the phase inversion process was carried out by means of the pervaporation method. The permeation flux and separation factor of pervaporation through the asymmetric polyimide membranes for a water 10wt%-ethanol 90wt% mixture at 75°C were 1.29kg·m-2·h-1 and 57, respectively. The esterification of carboxylic acid with ethanol accompanied by pervaporation was investigated using the asymmetric polyimide membrane in order to shift the equilibrium and increase the conversion of the esterification by removal of water from the reaction mixture. It was observed that the removal of water by pervaporation shifts the equilibrium further in favor of the ester formation and a conversion greater than the equilibrium value without pervaporation can be obtained. The degree of conversion at different molar ratios of acid to ethanol was calculated, using the rate equation of the esterification accompanied by pervaporation, and the effect of membrane performance on conversion was discussed.
