The effects of membrane type, the ratio of membrane area to reaction volume, and temperature were investigated. PERVAP 1201 membranes provided a higher water flux and higher selectivity than other hydrophilic membranes, but the highest fluxes were obtained using PDMS membrane, which selectively permeated isobutyl acetate compared to the other components. Increase in temperature and ratio of membrane area to reaction volume increased the conversion.
