| Application: | 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. |
| Features and Benefits: | Greener solvent |
| General description: | 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. We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is a Greener alternative to conventional solvents and chemicals. Click here  for more information. |
