Direct Synthesis of Diethyl Carbonate from CO2 and Ethanol Catalyzed by ZrO2/Molecular Sieve

The synthesis of diethyl carbonate starting from ethanol and carbon dioxide was studied. The ZrO 2 obtained by precipitation method was used as the catalyst. When the 3A molecular sieve was added as the co-catalyst, the DEC yield was effectively improved about 2.5-fold. The optimal mass ratio of ZrO...
