PRODUCTION PROCESS FOR ETHYL ACETATE

摘要

PURPOSE:To provide a vapor-phase production process for industrially useful ethyl acetate through highly stabilized operations in high efficiency by using a heterogeneous catalyst. CONSTITUTION:Using a solid catalyst of phosphotungstic acid of which a part of the protons are replaced with cesium cation, the catalytic reaction between ethylene and acetic acid are carried out in vapor phase to produce ethyl acetate. The heterogeneous catalyst has extremely high reaction activity and high durability and excellent reaction selectivity, thus ethyl acetate can be produced very economically with high industrial advantage.
