Description and Uses

Dimethyl carbonate is used as a solvent in organic synthesis and considered as a replacement for solvent like methyl ethyl ketone, tert-butyl acetate and parachlorobenzotrifluoride. It is involved as an intermediate in the preparation of diphenylcarbonate, which in turn is used as a key raw material for the synthesis of Bisphenol-A-polycarbonate. It is also used as a 'green' methylating agent involved in the methylation of aniline, phenols and carboxylic acids. It can be used as a fuel additive due to its high oxygen content. It also finds applications related to supercapacitors and lithium batteries.
