Properties：1,2-Dimethoxyethane is a colorless flammable liquid with strong ether odor. Melting point: -69℃, Boiling point: 84~86℃, Freezing point: -58℃, Flash point: -6℃. It can be miscible with water and alcohol, soluble in Hydrocarbon solvents. It is stable, not easy to react, but in the presence of high temperature acid catalyst, decomposition will occur. Under the action of oxygen, peroxides are generated. Light and heat promote the generation of peroxides, which are unstable and decompose into aldehydes, ketones, acids and other impurities.

Applications：1,2-Dimethoxyethane (DME), a high-performance aprotic polar solvent, boasts exceptional solubility, chemical stability, and compatibility, making it a versatile choice across multiple industrial sectors. Beyond its proven applications in chemical synthesis, electrochemistry, and material processing, it is also widely utilized as a high-efficiency solvent in the ink industry, delivering reliable performance for various printing formulations.

1. Chemical Synthesis & Processing

As an ideal solvent for polar organic reactions, 1,2-Dimethoxyethane facilitates smooth reaction kinetics and improved product yields in organic synthesis. It also serves as a high-efficiency gas absorbent for capturing specific gaseous components, a premium extraction agent for separating and purifying target substances, and a powerful paint remover for industrial surface treatment. Additionally, it acts as a compatible solvent for resins, nitrocellulose, and borane, and plays a critical role in the preparation of alkali metal oxides and other specialty chemicals.

2. Electrochemical & Battery Industry

1,2-Dimethoxyethane is a key non-aqueous electrolyte solvent, widely replacing water in electrochemical devices, rechargeable batteries (including lithium-ion batteries), and organic compound electrolytic reactions. Its excellent ion conductivity and electrochemical stability make it an indispensable material for enhancing battery performance, cycle life, and safety.

3. Ink Industry
