Description

Tetraglyme (Tetraethylene glycol dimethyl ether) is a high-purity, aprotic solvent with the molecular formula C₁₀H₂₂O₅. This colorless, low-volatility liquid is renowned for its exceptional solvating power, thermal stability, and inertness, making it a preferred choice for electrochemical and chemical synthesis applications. With a boiling point of 275°C and a flash point of 118°C, Tetraglyme is ideal for high-temperature processes. Its high dielectric constant and ability to dissolve a wide range of inorganic and organic compounds, including salts and polymers, make it invaluable in battery electrolytes, gas absorption, and as a reaction medium. Packaged under nitrogen to ensure purity and stability, our Tetraglyme meets the stringent demands of research and industrial applications.

Application

Tetraglyme is widely used as a solvent in lithium-ion and other advanced battery systems due to its ability to stabilize electrolytes and enhance ionic conductivity. It serves as a selective absorbent for acid gases like CO₂ and H₂S in natural gas processing. Additionally, Tetraglyme is employed in organic synthesis, particularly in phase-transfer catalysis and as a reaction medium for Grignard and polymerization reactions.
