O’Neill, Matthew F. published the artcileSustainable Synthesis of Dimethyl- and Diethyl Carbonate from CO2 in Batch and Continuous Flow-Lessons from Thermodynamics and the Importance of Catalyst Stability, SDS of cas: 100-70-9, the main research area is sustainable dimethyl diethyl carbonate CO2 batch lesson thermodn catalyst.
Equilibrium conversions for the direct condensation of MeOH and EtOH with CO2 to give dimethyl- and di-Et carbonate, resp., have been calculated over a range of exptl. relevant conditions. The validity of these calculations has been verified in both batch and continuous flow experiments over a heterogeneous CeO2 catalyst. Operating under optimized conditions of 140°C and 200 bar CO2, record productivities of 235 mmol/L·h DMC and 241 mmol/L·h DEC have been achieved using neat alc. dissolved in a continuous flow of supercritical CO2. Using our thermodn. model, we show that to achieve maximum product yield, both dialkyl carbonates and water should be continuously removed from the reactor instead of the conventionally used strategy of removing water alone, which is much less efficient. Catalyst stability rather than activity emerges as the prime limiting factor and should thus become the focus of future catalyst development.
