Diethylene Glycol (DEG, C₄H₁₀O₃) is a colorless, odorless, viscous liquid with hygroscopic properties and a sweet taste. As a vital chemical intermediate, it is widely used in polyester resins, antifreeze, plasticizers, solvents, and other applications, making it a key raw material in petrochemical and fine chemical industries.
Product Characteristics
High Boiling Point: ~245°C, suitable for high-temperature processes.
Hygroscopic: Absorbs moisture from the air.
Excellent Solubility: Miscible with water, alcohols, ketones, etc.
Low Toxicity: Less toxic than ethylene glycol (EG) but requires safe handling.
Applications
1. Polyesters & Resins
Production of unsaturated polyester resins (UPR) for coatings and fiberglass.
Diluent for epoxy resins.
2. Antifreeze & Refrigerants
Low-toxicity antifreeze formulations (mixed with EG).
Natural gas dehydrating agent.
3. Plasticizers & Solvents
Solvent for nitrocellulose, inks, and adhesives.
Textile lubricant.
4. Other Uses
Tobacco humectant, cosmetic base, gas purification.
