Dimethyl carbonate (DMC) is an important organic chemical intermediate. Because its molecular structure contains carbonyl group, methyl group, methoxy group and carbonylmethoxy group, it can be widely used in the organic synthesis reactions of carbonylation, methylation, methoxylation and carbonyl methylation, and is used in the production of polycarbonate, isocyanate, polyurethane, polycarbonate glycol, allyl diglycol carbonate A variety of chemical products, such as ester, naphthalene methylcarbamate (carbaryl), anisole, ammonium tetramethyl alcohol, long-chain alkyl carbonate, carbazide, malonate, malondiurane, diethyl carbonate, triphosgene, furazolidone, methyl hydrazinoate, methyl aniline carboxylate, etc. Because DMC is non-toxic, it can replace the highly toxic phosgene, methyl chloroformate, dimethyl sulfate, etc. as Methylating or carbonylating agent, it can improve the safety of production and operation and reduce environmental pollution. As a solvent, DMC can replace freon, trichloroethane, trichloroethylene, benzene and xylene for paint and cleaning solvent. As a gasoline additive, DMC can improve its octane number and oxygen content, thus improving its antiknock performance. In addition, DMC can also be used as an additive for detergents, surfactants and softeners. Due to its wide range of applications, DMC is known as the "new cornerstone" of organic synthesis.
