Dimethyl Carbonate | DMC | CAS No 616-38-6

Description:

Dimethyl carbonate (DMC), is a non-toxic, environmentally friendly performance, a wide range of chemical raw materials. It is an important organic synthesis intermediate. Dimethyl Carbonate /DMC is acting as a good solvent for coating, paints, ink, and adhesive substituting benzene, xylene, ethyl Acetate, butyl Acetate, acetone, butanone, Toluene.

It has a variety of reaction performances. In the production of the use of safe, convenient, less pollution, easy to transport and so on. As the toxicity of dimethyl carbonate is small, it is a promising “green” chemical product.

Ross Chem is the China Dimethyl carbonate supplier.

Applications：

• 1– A novel type of low toxicity solvents. It can substitute solvents. Such as toluene, xylene, ethyl acetate, butyl acetate, acetone or butanone in the paints and adhesive industry. It is an environmentally friendly green chemical product.
• 2—It is an excellent methylating agent, carbonylation agent, hydroxymethylation agent and methoxylation agent. It is also a kind of chemical raw material of wide application.
• 3— It is an ideal substitute for highly toxic products. Such as phosgene, dimethyl sulfate, and methyl chloroformate.
• 4— It can be used for synthesizing polycarbonate, diphenyl carbonate, and isocyanate and so on.
• 5— It can be used 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 carbamate drugs, pesticides (anisole).
• 7– It can be used as gasoline additives and lithium battery electrolytes and so on.
