Conversion of CO2 to cyclic carbonates by imidazolium salts at atmospheric pressure
Abstract
CO2, which causes global warming, is a naturally abundant, inexpensive, inert substance known as a non-toxic carbon (C1) source and value-added chemical, which can often be used as a building block for synthesis reactions. The conversion of CO2, which is difficult to use efficiently due to its kinetic inertia and thermodynamic stability, to cyclic carbonates with the help of a catalyst are the most promising studies. Therefore, in this study, 1-bütyl-3-methylimidazolium iodide ([Bmim]I) and 1-bütyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF6) imidazolium salts were used as catalysts in the conversion of CO2 into cyclic carbonates with epoxides. Conversion studies to cyclic carbonates were carried out under both high pressure and high temperature and atmospheric pressure. Ionic liquids, which provide high efficiency in the autoclave, also gave very good results in the atmospheric ambient. Optimization studies were carried out with the effect of time (2 hours and 24 hours) and temperature (60 °C and 100 °C) in the atmospheric ambient. It has been determined that this process, catalyzed by ionic liquids, is also promising for the chemical conversion of CO2 in the atmospheric ambient.
