Dimethyl carbonate DMC

Product Overview

Dimethyl Carbonate (DMC) — chemical names: dimethyl carbonate / methyl carbonate / carbonic acid dimethyl ester (CAS 616-38-6). DMC is a clear, mobile organic carbonate (also written dimethylcarbonat, propylenecarbonat is a different carbonate — note to avoid confusing the two) used both as a green solvent and as a versatile reagent for methylation, carbonylation and carbonate synthesis. It is considered a low-toxicity, environmentally preferable alternative to methylating reagents such as dimethyl sulfate or phosgene derivatives.

Major Applications & Uses

Green solvent: DMC replaces toluene, xylene, MEK and other VOC solvents in paints, adhesives, and coatings — marketed as a dimethyl carbonate green solvent and general dimethyl carbonate solvent.
Methylation & carbonylation agent: DMC is an efficient methylating reagent (safer substitute for dimethyl sulfate) and is used in synthesis of pharmaceuticals, agrochemicals and fine chemicals.
Polycarbonate & diphenyl carbonate synthesis: key intermediate for non-phosgene polycarbonate routes.
Lithium battery electrolytes & fuel additives: used as an additive/solvent in specific electrolyte blends and fuel oxygenates.
Laboratory & specialty uses: reagent for methoxylation, hydroxymethylation and carbamate preparation.

1. A novel type of low toxicity solvents and can substitute solvent such as toluene, xylene, ethyl acetate, butyl acetate, acetone or butanone in paints and adhesive industry, and is environmentally friendly green chemical products.

2. It is excellent methylating agent, carbonylation agent, hydroxymethylation agent and methoxylation agent and is a kind of chemical raw material of wide application.
3. It can be used as ideal substitute of highly toxic product such as phosgene, dimethyl sulfate, and methyl chloroformate.
4. It can be used for synthesizing polycarbonate, diphenyl carbonate, and isocyanate and so on.
5. In the field of medicine, it can be for the synthesis of anti-infective drugs, anti-inflammatory medicines, vitamin-class medicines and central nervous system drugs.
6. In the field of pesticides, it can be mainly used for the production of methyl isocyanate, thereby producing some carbonate drugs, pesticides (anisole).
7. It can be used as gasoline additives and lithium battery electrolyte and so on.
