A detailed alkali catalytic preparation of diethyl carbonate (DEC) from diethyl oxalate (DEO) via gaseous phase decarbonylation was investigated in the paper. The detailed preparation of diethyl carbonate from diethyl oxalate via gaseous decarbonylation with alkali catalysts was studied in this paper. K2CO3/AC catalyst prepared by the incipient wetness impregnation shows the favorable catalytic performance, and the optimum potassium loading is 6 wt%.

The synthesis of diethyl oxalate from ethyl nitrite and carbon monoxide was studied in a continuos flow micro fixed-bed reactor at atmospheric pressure. This study reveals that the pore structure of the supports remarkably affects the palladium dispersion of the catalysts and alters the CO adsorption behavior, therefore, dramatically affect the catalytic performance. In the case of CO+C2H5ONO reactions, diethyl oxalate was efficiently formed over the 1 wt.% Pd/α-Al2O3-1 catalyst.
