Dimethyl carbonate
Dimethyl carbonate (CAS 616-38-6), with a molecular formula of C3H6O3 and a molar mass of 90.08 g/mol, is a versatile organic compound. It is a clear, colourless liquid known for its low toxicity and biodegradability compared to other methylating agents. Dimethyl carbonate serves as a valuable reagent and solvent in various chemical syntheses, including the production of polycarbonates and as a methylating or acylating agent.
Solvent and Reagent in Organic Synthesis
Dimethyl carbonate is widely employed as a green solvent and a reactant in organic chemistry. Its ability to act as a methylating and carbonylating agent makes it an attractive alternative to more hazardous chemicals.
Polycarbonate Production
It is a key intermediate in the synthesis of polycarbonates, offering a safer and more environmentally friendly production route compared to traditional phosgene-based methods.
Electrolyte Component for Batteries
Dimethyl carbonate is a common component in electrolytes for lithium-ion batteries, contributing to their performance and stability.
Methylating Agent
Used for the methylation of phenols, amines, and carboxylic acids, it provides a more sustainable option for introducing methyl groups in organic molecules.
