Dimethyl carbonate may be used to synthesize:• Methyl phenyl carbonate by transesterification with phenol.• Diphenyl carbonate by transesterification with methyl phenyl carbonate.• Methyl carbamates, a raw material for isocyanate synthesis.• Tetramethoxysilane by reacting with silica at 550-600K.
Dimethyl carbonate (DMC) is a versatile, non-toxic, biodegradable reagent with tunable chemical reactivity. It serves as a green alternative to dimethyl sulfate or methyl halides and phosgene for methylation and carboxylation reactions. The base-catalyzed reaction between carbon dioxide and methanol to form DMC has been studied. Various thermodynamic parameters of DMC have been reported.
