The process of synthesizing dimethyl carbonate through the urea methanolysis reaction has been less attractive because it has a low yield and a higher risk of toxicity than the direct synthesis process. However, the urea methanolysis reaction can be an alternative because it has several advantages: urea and methanol raw materials have low prices and are easy to obtain and handle. In this review, a literature study was conducted to review the operating conditions, catalyst selection, and shortcomings of the urea methanolysis process in synthesizing dimethyl carbonate and methylcarbamate based on current research references. The study results indicate that the development of the urea methanolysis reaction research still requires steps to develop a range of operating conditions to obtain a more significant yield so that later it can become an alternative route for operating on an industrial scale.
