Abstract

The esterification reactions of succinic acid with alcohols are studied in a membrane reactor using acid-resistant mordenite membranes and cation-exchanged resin as catalyst. The microstructures of mordenite membranes before the reaction and after 10 times reaction runs are characterized by X-ray diffraction (XRD) and scanning electronic microscope (SEM). The influences of molar ratio of acid to alcohol, synthesis temperature, catalyst amount and the ratio of membrane area to reaction volume on the esterification are studied. The reaction equilibrium is broken and shifts to the right side due to by-product water removal by mordenite membranes. The conversion of succinic acid can achieve at almost completion at a close ideal mole ratio. The reusability of zeolite membranes in the reactions is also investigated.
