General description

Ethyl methyl carbonate (EMC) is a low viscosity solvent, generally prepared by the esterification of chloroformate with ethanol. It can also be prepared by transesterification of dimethyl carbonate (DMC) with ethanol.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

EMC is majorly utilized as a co-solvent in the nonaqueous electrolyte. It enhances the energy density and discharge capacity of lithium-ion batteries.
