The one-pot ethyl acetate syntheses: The role of the support in the oxidative and the dehydrogenative routes
Abstract Both the dehydrogenative and the oxidative routes for the one-pot ethyl acetate synthesis from ethanol were studied using physical mixtures of Cu/ZnO/Al2O3 or PdO/m-ZrO2 with three differentExpand
