Abstract

Dimethyl carbonate (DMC) is an environmentally friendly organic compound utilized in multiple applications such as production of lithium-ion batteries, fertilizers and fuel additives. It has been produced by traditional synthesis methods including phosgenation, oxidative carbonylation and transesterification. These methods offer high yields, and selectivity. However, they have several drawbacks related to safety, environmental impact and economic feasibility. Due to the given issues, the researchers and industry have been seeking alternative methods. Among them, the direct synthesis from carbon dioxide and methanol method emerges as a greener, safer and sustainable alternative. Nevertheless, this method faces significant challenges resulting in low reactant conversion and product yield. To address these limitations various strategies have been proposed and developed. This thesis is a literature review that analyzes the latest strategies employed to improve the synthesis. The key strategies include utilization of various catalytic systems and dehydrating agents including heterogeneous and homogeneous catalysts with chemical and physical dehydrating agents. Additionally, the thesis explores the optimization of reaction kinetics by discussing the impact of kinetic parameters and models. Altogether, these strategies offer a foundation to overcome existing limitations by enhancing the conversion and yield of the reaction for future developments.
