Diethyl carbonate

Diethyl carbonate (CAS 105-58-8), also known as DEC or Eufin, is a low-toxicity carbonate ester solvent used in pharmaceutical manufacturing, battery electrolyte production, and specialty chemical synthesis.

Where is Diethyl carbonate used?

• Lithium-ion battery electrolytes: primary co-solvent improving ionic conductivity and low-temperature performance
• Pharmaceutical manufacturing: reaction solvent and carbonylation reagent for carbamates, polycarbonates and APIs
• Food and flavour: beverage preservative and fermentation inhibitor in wine and fruit juices
• Specialty chemicals: methylation and ethylation agent in catalyst preparation and fine chemical synthesis
• It is a preferred alternative to more hazardous polar aprotic solvents in regulated production environments.

Commercial specifications

• Standard commercial grades: technical, anhydrous, high-purity (battery use)
• Clear liquid in drums, IBCs and bulk tanker quantities
