Abstract
The widespread use of ethyl acetate in the paint, food and chemical industries has resulted in large quantities of emissions that pose a threat to the environment and human health. Catalytic oxidation is suitable as an efficient method without secondary pollution to degrade ethyl acetate. In this review, we present the catalytic oxidation of ethyl acetate in terms of mechanism, catalysts, process influencing factors and mixed oxidation. The effects of acidic sites and oxygen species on the oxidation process of ethyl acetate and the factors affecting intermediate products are discussed. Comparative overviews of the progress and performance of noble metal, transition metal and monolithic catalysts in the catalytic oxidation of ethyl acetate are presented respectively. The effects of space velocity, feed concentration and water on the conversion of ethyl acetate are illustrated. The mixed oxidation between ethyl acetate and other VOCs is summarized. Finally, we recommend the future trends and challenges in the catalytic oxidation of ethyl acetate.
