Dimethyl carbonate (DMC) is a versatile compound that represents an attractive eco-friendly alternative to both methyl halides (or dimethyl sulfate) and phosgene for methylation and carbonilation processes, respectively.

From a chemical engineering standpoint it can act as a substitute for:
1. A non-phosgene process for making polycarbonates- the transesterification of dephynyl carbonate with bisphenol-A (the DMC is used to synthesis the diphenyl carbonate)
2. production of isocyanate for polyurethane; (carbamates can be synthesized from DMC)
3. substitute for dimethyl sulfate and methyl chloride in methylation reactions
4. direct synthesis of tetramethoxysilane from silica and DMC
The DMC can be prepared using non-phosgene reactions, thus eliminating the use of more hazardous chemicals in most of these reactions.

it's another possibility to add to one's synthetic arsenol
