Dimethyl carbonate (DMC) can be applied as a greener alternative to more hazardous materials, e.g. phosgene or dimethyl sulfate. Herein, one-pot synthesis of DMC from propylene oxide, methanol and CO2 using alkali halide catalysts under mild conditions was studied. Addition Zn powder the K2CO3-NaBr-ZnO catalyst system seen increase selectivity 19.8% (TOF = 39.0 h?1) 40.2% 78.1 at 20 bar 160 °C ...
