Electrochemical Fixation of Carbon Dioxide for Synthesis Dimethyl Carbonate in Ionic Liquid BMimBr
Abstract:
In the one compartment electrochemical cell equipped with platinum electrodes electrochemical fixation carbon dioxide was conducted under ambient conditions. Ionic liquid BMimBr is supporting electrolyte. The aimed product dimethyl carbonate was electrosynthesized in a dialkylimidazolium ionic liquids-propylene oxide-methanol system under normal temperature and pressure. The result indicated that the highest yield of 37.8 % was obtained in the condition of working temperature 30 °C, electrolytic voltage 5.5 V, the mass of CH3OH 0.484 mol, propylene oxide 0.052 mol and bmimBr 0.059 mol.
