Esterification of Acetic Acid by Flow-Type Membrane Reactor with AEI Zeolite Membrane.

ABSTRACT: AEI-type zeolite membrane for dehydration was prepared, and a flow-type membrane reactor for the esterification of acetic acid and ethanol by AEI membrane was developed. A synthesized AEI membrane had suitable molecular sieving property for gas separation (H₂/i-butane and CO₂/CH₄) and pervaporation (H₂O/acetic acid). AEI membrane showed H₂O permeance of 6.2 × 10^-7 mol m^-2 s^-1 Pa^-1 with a separation factor of 67 at 363 K for the equimolar mixture of H₂O/acetic acid. AEI membrane maintained stable performance under acidic conditions. The yield of ethyl acetate at 363 K in a flow-type membrane reactor with AEI membrane successfully exceeded the equilibrium of 69.1%, reaching 89
