Catalytic poly (vinyl alcohol) functionalized membranes obtained by gamma irradiation
MH Casimiro, AG Silva, JV Pinto, AM Ramos… - Radiation Physics and …, 2012 - Elsevier
Polymeric catalytic membranes bearing sulfonic acid functions have been prepared by
mutual gamma irradiation at a 60Co source, of poly (vinyl alcohol)(PVA) membranes and
methanesulfonic acid. The effect of various synthesis conditions on membranes' physical–
chemical properties and catalytic activity in the esterification reaction between acetic acid
and isoamyl alcohol to obtain isoamyl acetate (banana flavor), was evaluated. The
membranes were characterized by ATR-FTIR, TPP, AFM and SEM. Water contact angle …
