Oxidative Esterification of Ethanol over Oxide Catalysts

Abstract
Oxidative esterification of ethanol has been studied over various oxide catalysts. Acetaldehyde was easily formed by oxidative dehydrogenation, and reacted further with remained ethanol and oxygen to produce ester. Among single oxides, Bi2O3, MoO3, and Sb2O4 showed the highest selectivity and yield for ethyl acetate formation, respectively. The ethyl acetate yield was highest and complete oxidation was extremely low over MoO3–Sb2O4 system.
