Dimethyl carbonate, referred to as DMC, was listed as a non-toxic product in Europe in 1992. It is a low-toxic, environmentally friendly and widely used chemical raw material. Dimethyl carbonate can be used to make lithium battery electrolytes, can replace phosgene as a carbonylating agent, and can also replace dimethyl sulfate as a methylating agent. It can even become one of the most promising gasoline additives to replace MTBE because of its high oxygen content (up to 53% oxygen content in the molecule), excellent octane number improvement, no phase separation, low toxicity and rapid biodegradability. At the same time, dimethyl carbonate is also an important green and environmentally friendly solvent that can replace a variety of solvents. Compared with some common solvents, dimethyl carbonate has excellent solubility and low toxicity. It also has the characteristics of high flash point, low vapor pressure and high lower explosion limit in air. It is a green solvent that combines cleanliness and safety.
