Basic Information

Product Description

Product Name：Tetracthy lene Glycol Dimethyl Ether (TETREDM)

CAS No: 143-24-8

Form: liquid

Product Application

Lithium/Sodium Batteries (Core High-End Application):

Electrolyte Solvent: A key component in electrolytes for sodium-sulfur (Na-S) batteries, lithium-sulfur (Li-S) batteries, some lithium-ion batteries, and next-generation metal (Li/Na) batteries. It effectively dissolves and dissociates conducting salts, enabling high ionic conductivity while offering relative stability towards metal anodes. Ultra-pure, ultra-dry, low-acid "Battery Grade"​ TEGDME is in high demand.

Organic Synthesis & Chemical Industry:

Aprotic Polar Reaction Solvent: Used in Grignard reactions, Wittig reactions, anionic polymerizations, and reductions.

Phase-Transfer Catalyst (PTC): Facilitates reactions between aqueous and organic phases.

Gas Absorbent: Used in acid gas (e.g., CO₂, H₂S) removal, particularly in natural gas purification.

Polymer Industry:

Solvent for Anionic Polymerization: For synthesizing polymers with specific architectures, such as styrene-butadiene-styrene block copolymers.

Polymer Plasticizer and Processing Aid.

Other Specialty Fields:

Specialty Coatings & Inks: Serves as a high-boiling, high-performance coalescent or solvent.

Chemical Analysis: Used as a stationary phase in gas chromatography.

200kg/drum

Storage

Must be stored in a cool, dry, well-ventilated area with strict moisture protection. Storage under an inert atmosphere (e.g., nitrogen blanket) is recommended for high-purity grades, especially battery grade. Keep away from heat and oxidizers.
