methanol from organic solvents by FAU zeolite membranes were investigated to gather fundamental knowledge about membrane separation assisted transesterification. The FAU zeolite membranes showed methanol-selective permeations from azeotrope forming methanol-methyl acetate and methanol-methyl methacrylate mixtures. Pervaporation performances of FAU zeolite membranes were evaluated also with transesterification mixtures formed with the acidic ion-exchange resin, Amberlyst 15, and with synthetic quaternary mixtures.
