“…5,6 At present, some synthetic methods for DEC have been studied, such as phosgenation of ethanol, 7 transesterification of carbonates, 8 oxidative carbonylation of ethanol, 10,11 and ethanolysis of CO 2 [12][13][14][15] or urea. [16][17][18][19][20][21] However, the phosgenation process is becoming obsolete gradually because it involves the use of an extremely dangerous chemical phosgene. There are also some problems in the oxidative carbonylation of ethanol, e.g.…”

“…[1] DEC is an environmentally friendly and biodegradable, which can slowly hydrolyze to carbon dioxide and ethanol. [2] Therefore, DEC is used as a fuel additive due to its high oxygen content of 40.6 % and high energy content, [3] lower vapor pressure and more favorable gasoline-water partition coefficient compare to dimethyl carbonate and ethanol. [4] Therefore, the synthesis of DEC has received extensive attention.…”

Series of La‐doped Mg−Al composite oxides were prepared by co‐precipitation method and used as catalysts for the synthesis of diethyl carbonate (DEC) via transesterification of ethylene carbonate (EC) with ethanol (EtOH). SEM, XRD, FT‐IR and XPS results confirmed that the introduction of La enhanced the interaction with MgO. The 8 mol % La‐doped Mg−Al composite oxide (calcined catalyst named HTC‐0.8 La) produced strong interactions and improved lattice oxygen content (27.84 %). Based on the N2 adsorption‐desorption and CO2‐TPD results, the HTC‐0.8 La catalysts possessed abundant multistage mesoporous structure, high strong base density and strength (0.941 mmol ⋅ g−1). Therefore, the HTC‐0.8La catalyst exhibited high catalytic activity with 58.5 % yield of DEC and 94.7 % selectivity to DEC (EC: EtOH molar ratio=1 : 6, reaction time=1.5 h, reaction temperature=150 °C and catalyst amount=3.2 wt %). Based on the correlation between catalytic activity and alkalinity, the yield of DEC was positively and linearly related to the strong alkali density of the catalyst. After five replicate experiments, the DEC yield after recovery and roasting reached 54.1 %, indicating that HTC‐0.8La is a renewable heterogeneous catalyst.
