Triethylene glycol (TEG)

Triethylene glycol (TEG):

Triethylene glycol (TEG) is a colorless, odorless, viscous liquid with strong hygroscopic (water-absorbing) properties. Its chemical formula is C6H14O4C_6H_{14}O_4C6​H14​O4​, and it is commonly used in applications that require moisture control or involve high-temperature stability.

Uses of Triethylene Glycol

1. Gas Dehydration: TEG is widely used in natural gas processing to dehydrate gas streams by absorbing moisture, preventing corrosion and ice formation in pipelines.
2. Industrial Humectant: Helps retain moisture in applications where dryness could cause issues, such as in air conditioning systems and humidifiers.
3. Disinfectants and Sanitizers: Effective in killing airborne bacteria, it is sometimes used in disinfectant formulations and air sanitizers.
4. Plasticizers: Used to enhance flexibility and durability in certain resins, polymers, and plastic products.
5. Hydraulic and Brake Fluids: Added to fluids for hydraulic and braking systems due to its high boiling point and chemical stability.
6. Solvent: Utilized in chemical processes and as a carrier solvent for various substances.
