Ethyl Acetate Dehydration Equipment

The manufacture of ethyl acetate traditionally relies on four primary production processes: esterification of acetic acid and ethyl ester, acetaldehyde condensation, catalytic dehydrogenation of ethanol, and adductive esterification of acetic acid and ethylene. However, the conventional process has faced challenges, including lower production technology standards, elevated costs, and subsequent supply-demand imbalances. These issues have led to reduced production, decreased profitability, and, in some cases, ceased production altogether.

Hence, the pursuit of a novel separation technology with low energy consumption, minimal environmental impact, and exceptional separation efficiency has emerged as a prominent trend in industrial production. Employing the pervaporation technique, ethyl acetate binary and ternary crude products can be efficiently separated using inorganic molecular sieve membranes, distinguished by their superior chemical stability and separation performance.
