Dimethyl carbonate (DMC) is an important organic chemical intermediate. Because its molecular structure contains carbonyl, methyl, methoxy and carbonylmethoxy, it can be widely used in carbonylation, methylation, methyl Organic synthesis reactions such as oxygenation and carbonyl methylation for the production of polycarbonate, isocyanate, polyurethane, polycarbonate diol, allyl diethylene glycol carbonate, naphthyl methylcarbamate ( Carbine), anisole, tetramethyl alcohol ammonium, long-chain alkyl carbonate, carbohydrazide, malonate, propanediurane, diethyl carbonate, triphosgene, furazolidone, methyl carbazate Ester, methyl aniline formate and other chemical products. Since DMC is non-toxic, it can replace the highly toxic phosgene, methyl chloroformate, dimethyl sulfate, etc. as a methylating agent or carbonylating agent, improving the safety of production operations and reducing environmental pollution. As a solvent, DMC can replace freon, trichloroethane, trichloroethylene, benzene, xylene, etc. for paint coatings, cleaning solvents, etc. As a gasoline additive, DMC can increase its octane number and oxygen content, thereby improving its antiknock. In addition, DMC can also be used as an additive for detergents, surfactants and softeners. Due to its wide range of uses, DMC has been hailed as the "new cornerstone" of today's organic synthesis.
