일반 설명

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.

애플리케이션

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.

Complex Hydrides: A New Category of Solid-state Lithium Fast-ion Conductors

Research and development of solid-state lithium fast-ion conductors is crucial because they can be potentially used as solid electrolytes in all-solid-state batteries, which may solve the safety and energy-density related issues of conventional lithium-ion batteries that use liquid (farmable organic) electrolytes.
