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

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 (H/-butane and CO/CH) and pervaporation (HO/acetic acid). AEI membrane showed HO permeance of 6.
