dimetylkarbonat

Dimethyl carbonate (DMC) is an organic compound with the chemical formula (CH₃O)₂CO. It is a clear, colorless liquid with a mild odor. DMC is a carbonate ester and is considered a versatile and environmentally friendly chemical.

DMC can be synthesized through several methods, including the phosgenation of methanol and the transesterification of methanol with urea or carbon dioxide. The latter methods are preferred due to their reduced environmental impact.

One of the primary applications of dimethyl carbonate is as a solvent. It is a good solvent for many organic and inorganic compounds and is often used as a substitute for more toxic solvents like phosgene or dimethyl sulfate in various chemical processes. Its low toxicity and biodegradability make it an attractive green solvent.

DMC also serves as a methylating and carbonylating agent in organic synthesis. It is used in the production of polycarbonate plastics, where it reacts with bisphenol A. Additionally, it finds use as an electrolyte component in lithium-ion batteries, contributing to their performance and safety. In the fuel industry, DMC can be used as a fuel additive to increase octane ratings and reduce emissions. Its properties allow it to be a part of various industrial formulations.
