Now-a-days, an increased concentration of carbon dioxide, being one of the green house gases, in the atmosphere has raised remarkable environmental issues.
In the purview of climate change, the transportation, burning of fossil fuels, and cement manufacturing industries are observed to be prime contributors of global warming, which thrust research on an exploration of a new methodologies for CO2 sequestration and utilization among the researchers across the globe. Among the various innovative approaches, a liability to resource transformation of CO2 has been well-thought-out as a potential methodology as it treats CO2 as a commodity that can yield a profit.
We have effectively used Supercritical CO2 as solvent for low temperature reaction systems in enzymatic synthesis of food grade esters like butyl butyrate as well as high temperature reaction like synthesis of biodiesel from triglycerides and alcohols.
Results are very promising when Supercritical CO2 plays the dual role of solvent as well as reactants for conversion of epoxides to cyclic carbonates.
