Packaging and shipping
Diethyl Carbonate (DEC, CAS 105-58-8) is a high-purity, eco-friendly organic compound known as a “green solvent” with low toxicity and good biodegradability. It appears as a colorless transparent liquid with molecular formula C₅H₁₀O₃ and molecular weight 118.13, featuring a density of 0.975 g/mL at 20 °C, melting point -43 °C, boiling point 126-128 °C, and flash point 31 °C (closed cup).
As a key component in lithium-ion battery electrolytes, DEC enhances low-temperature performance and electrochemical stability when blended with other carbonates like EC and DMC. It also acts as an efficient alkylating and carbonylating agent in pharmaceutical and chemical synthesis, supporting the production of intermediates, polycarbonates, and fine chemicals while reducing reliance on toxic reagents. In coatings, inks, and cleaning formulations, DEC serves as a low-VOC solvent with excellent dissolving capacity, improving product safety and environmental compatibility.
Our DEC is offered in industrial, battery, and pharmaceutical grades, backed by a stable supply chain and full compliance documentation, meeting international quality standards for reliable performance across diverse industrial applications.
Product Description
Diethyl Carbonate (DEC, CAS 105-58-8) is a high-purity, eco-friendly organic compound classified as a “green solvent,” characterized by low toxicity, good biodegradability, and stable chemical properties.
It appears as a colorless transparent liquid with a molecular formula of C₅H₁₀O₃ and a molecular weight of 118.13, with a density of 0.975 g/mL at 20 °C, a melting point of -43 °C, a boiling point of 126-128 °C, and a closed-cup flash point of 31 °C.
Available in industrial, battery, and pharmaceutical grades, our DEC is produced under strict quality control, supported by a stable supply chain and complete compliance documents to meet international standards for diverse industrial applications.
As a key component in lithium-ion battery electrolytes, DEC is blended with other carbonates such as EC and DMC to enhance the battery’s low-temperature performance and electrochemical stability, extending cycle life and improving safety.
It also acts as an efficient alkylating and carbonylating agent in pharmaceutical and chemical synthesis, used to produce intermediates, polycarbonates, and fine chemicals while reducing reliance on toxic reagents.
In coatings, inks, and cleaning formulations, DEC serves as a low-VOC solvent with excellent dissolving power, effectively replacing harmful traditional solvents to boost product safety and environmental compatibility.
For usage, it is handled under dry, well-ventilated conditions in battery manufacturing, employed under controlled temperature and pressure in chemical reactions, and applied directly or diluted in industrial cleaning processes.
