Dimethyl carbonate (DMC) is a chemical raw material with low toxicity, excellent environmental protection performance and wide use. It is an important organic synthesis intermediate. Its molecular structure contains carbonyl, methyl, methoxy and other functional groups, and has a variety of reaction properties. It is safe, convenient, less pollution, and easy to transport in production. Due to its low toxicity, dimethyl carbonate is a "green" chemical product with development prospects.
