Dimethyl Carbonate Uses

VOC Exempt Solvent – Dimethyl Carbonate (DMC) received its Federal VOC exemption on January 13, 2009. As of March 1, 2011 it is exempt in 42 States. It is flammable with a flash point 17 ºC (63 ºF). (Last updated: 03.2011; please contacts us for the most up to date information on the VOC exemption state by state.)

Paints and Coatings – Dimethyl Carbonate can be used as VOC exempt solvent in many paints and coatings. DMC is a fast evaporating polar solvent. It can replace esters, glycol ethers and ketones in formulations.

Reactive Intermediate – DMC can be used as a methylating and carbonylating reagent in organic synthesis.

Fuel Additive – Because of its high oxygen content, DMC can be used as a fuel additive.

Li-ion Battery – Lithium ion battery electrolytes use organic carbonates such as diethyl carbonate and complexes of lithium ions.
