Product Description
Dimethyl carbonate is abbreviated as DMC. At room temperature, it is a colorless transparent liquid with a pungent odor. Its relative density (d204) is 1.0694. The melting point is 4℃, the boiling point is 90.3℃, the flash point is 21.7℃ (open) and 16.7℃ (closed) (Chemicalbook). The refractive index (nd20Chemicalbook) is 1.3687. It is flammable and non-toxic. It can be mixed with almost all organic solvents in any proportion, and is slightly soluble in water. It can be used as a methylating agent. Compared with other methylating agents, such as iodomethane and dimethyl sulfate, dimethyl carbonate has less toxicity and can be biodegraded.

The molecular structure of dimethyl carbonate (DMC) is unique (CH3O-CO-OCH3), containing carbonyl, methyl, methoxy and carbamino-methoxy groups. Therefore, it can be widely used in various organic synthesis Chemicalbook reactions such as carbonylation, methylation, methoxylation and carbamino-methylation, and has very extensive applications. It is mainly used as a carbonylation and methylation reagent, a gasoline additive, and a raw material for synthesizing polycarbonate (PC), etc. The large-scale production of DMC has developed along with the non-phosgene synthesis process of polycarbonate. Its applications are as follows:
1.A new type of low-toxic solvent can replace toluene, xylene, ethyl acetate, butyl acetate, acetone or butanone in the paint and adhesive industries. It is an environmentally friendly and green chemical product.
2. Excellent methylating agents, carbonylating agents, hydroxymethylating agents and methoxylation agents have been widely used in fields such as food antioxidants and plant protectants, and are a versatile type of chemical raw material.
3. Ideal substitutes for highly toxic substances such as phosgene, dimethyl sulfate, and methyl chloroformate.
4. Synthesize polycarbonate, bisphenol carbonate, isocyanate, etc.
5. In the field of medicine, it is used for synthesizing anti-infective drugs, antipyretic and analgesic drugs, vitamin drugs, and drugs for the central nervous system.
6. In the field of pesticides, it is mainly used to produce methyl isocyanate, which in turn is used to produce certain carbamate drugs, insecticides (benzophenone).
7. Gasoline additives, lithium battery electrolyte, etc.
