- Abstract
- The production of cyclic carbonates is pivotal in carbon capture and utilization (CCU), providing an opportunity to utilize recycled CO2. Ethylene carbonate (EC) holds significance among cyclic carbonates in industrial settings due to its extensive applications in lithium-ion batteries and industrial lubricants and as a precursor for green polycarbonate production. However, the current synthesis of EC relies on toxic, fossil-based epoxide reactants, which poses sustainability challenges. To meet the growing demand for green chemistry, three greener alternative pathways for EC synthesis have been proposed, involving the reaction of carbon-based reactants (CO2, urea, and dimethyl carbonate) with ethylene glycol (EG) derived from biodiesel waste. This Perspective addresses key inquiries surrounding alternative EC synthesis pathways through quantitative and qualitative assessments. Specifically, we elucidate (a) possible sustainable routes, (b) current advances in the first principle of kinetic and operational methods, and (c) differences in reactions from the perspectives of thermodynamics, safety, and greenness of production. Notably, the direct carboxylation of CO2 with EG emerges as a promising green synthesis route, but challenges persist, such as catalyst development and water inhibition. Finally, future prospects for overcoming challenges in the green manufacturing of EC are discussed, providing insights into advancing CCU. © 2023 American Chemical Society.
