Triethylene Glycol TEG CAS 112-27-6
Triethylene Glycol (TEG), with CAS number 112-27-6, is a colorless, transparent and viscous liquid without odor, with a slightly sweet taste, and has strong hygroscopicity. It has low volatility, good thermal stability, is slightly toxic, and has low skin irritation.
Triethylene glycol (CAS 112-27-6) is packed in sealed 200L steel drums or HDPE IBC totes. Store in cool, dry, ventilated warehouse below 40°C, keep containers tightly closed to avoid moisture absorption. Keep away from direct sunlight, heat and strong oxidants.

1. Natural gas / oilfield gas dehydration (main application)
Natural gas, associated gas, CO₂ gas purification liquid desiccant
- Selectively absorbs water vapor in the gas and does not absorb hydrocarbons; after saturation, heat regeneration can be repeated for use
- Prevents the formation of hydrates in pipelines and pipeline corrosion, is a mainstream dehydration agent in the oil and gas industry.
2. High boiling point industrial solvents
- Aromatic hydrocarbon extraction solvents, for separation in petrochemicals
- Nitrocellulose, resin, rubber, ink, paint, dye solvents, high boiling point and difficult to volatilize
- Organic synthesis reaction medium
3. Plasticizer intermediates
Triethylene glycol is used in the synthesis of triglycerol ester plasticizers, for PVC, polyvinyl acetate resin, glass fiber sheets; the plasticizer has low migration rate and good low-temperature performance as a competitive chemical.
4. Special fluid raw materials
Triethylene glycol can be used to prepare automotive brake fluid and hydraulic oil; provides low-temperature stability, high boiling point and not easy to vaporize, suitable for high-temperature conditions.
5. Humectant, gas-phase antibacterial agent
- Tobacco humectant, prevents tobacco leaves from drying and cracking
- Daily use, air disinfection: gas-phase sterilization, used in air disinfection systems
- Textile auxiliaries, fiber lubricant.
6. Other subdivisions
- Gas chromatography stationary liquid
- Pharmaceutical extraction solvent
- Liquid desiccant for air dehumidification systems.
