Application of FAU zeolite membranes to alcohol/acrylate mixture systems

• FAU zeolite membranes were prepared by secondary growth method.
• Pervaporation performances of FAU zeolite membranes were examined.
• Sf > 1000, flux > 2 kg m−2 h−1 were obtained in methanol and methyl methacrylate separation.
• Quaternary mixtures of transesterification were treated by FAU zeolite membranes.
• Significantly high methanol selectivity from methyl methacrylate was obtained.

Faujasite (FAU) zeolite membranes were prepared by secondary growth method. Separations of 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.
