Dimethyl carbonate is abbreviated as DMC. At room temperature, it is a colorless, transparent, pungent odorous liquid. The relative density (d204) is 1.0694, the melting point is 4C, the boiling point is 90.3C, the flash point is 21.7C (opening), 16.7C (closed) ), refractive index (nd20Chemicalbook) 1.3687, flammable, non-toxic. It can be mixed with almost all organic solvents such as alcohol, and ester in any ratio, and is slightly soluble in water. Can be used as a methylating agent. Compared with other methylation reagents, such as methyl iodide and dimethyl sulfate, dimethyl carbonate is less toxic and biodegradable.

Applications:
1. A new type of low-toxicity solvent can replace solvents such as toluene, xylene, ethyl acetate, butyl acetate, acetone or methyl ethyl ketone in the paint and adhesive industries. It is an environmentally friendly green chemical product.
2. Good methylating agent, carbonylating agent, hydroxymethylating agent and methoxylating agent are a kind of chemical raw materials with a wide range of uses.
3. Chemicalbook wants to replace phosgene, dimethyl sulfate, methyl chloroformate and other highly toxic drugs.
4. Synthetic polycarbonate, diphenyl carbonate, isocyanate, etc.
5. In medicine, it is used to synthesize anti-infective drugs, antipyretic and analgesic drugs, vitamin drugs, and central nervous system drugs.
6. Pesticides are mainly used to produce methyl isocyanate, and then to produce certain carbamate drugs and insecticides (anisole).
7. Gasoline additives, lithium battery electrolyte, etc.
