Abstract
Cation ionexchange resin particles CERP/polyethersulfone PES hybrid catalytic membranes were prepared by immerse phase inversion for the esterification of different free fatty acids FFAs such as dodecanoic acid tetradecanoic acid hexadecanoic acid and octadecadienoic acid with methanol The membranes were characterized by SEM ionexchange capacity and swelling degree test It is found that dodecanoic acid has the highest FFAs conversion among the four acids for its stronger acidic and reactivity Different effects of membrane annealing temperature reaction temperature molar ratio of methanol to FFAs and catalytic membrane loading on the esterification were investigated by the esterification of dodecanoic acid with methanol The dodecanoic acid conversion reaches 975 under the optimal condition when the esterification reaction lasted for 8 h
