다국어 초록 (Multilingual Abstract)

Dimethyl carbonate (DMC) was synthesized in excellent yield by direct physically or chemically adsorption of carbon dioxide on [EmimOH][NTf2] IL in presence of SmOCl and super base. Meaningfully, novel ternary catalyst system was found to display noticeable conversion of methanol (13.01%) with excellent selectivity (99.13%) towards DMC. The interaction of CO2 with IL in presence of superbase was discussed by FT-IR and 13C characterization as well as catalytic reactivity was proved by predictable mechanism. Various conditions such as reaction temperature, pressure and time were investigated for DMC.
