Triethylene glycol

Triethylene glycol (TEG) is a clear, colorless, odorless, viscous liquid with low volatility and a high boiling point of approximately 287 °C. It is a polyether alcohol—specifically, a member of the glycol family—and functions as a hygroscopic solvent and chemical intermediate. TEG is widely used in natural gas dehydration units due to its affinity for water, and serves as a precursor in the synthesis of plasticizers, unsaturated polyester resins, and certain surfactants. Its primary application areas include polymers, coatings, and as a solvent or humectant in specialty formulations such as hydraulic brake fluids and textile auxiliaries.

triethylene glycol is a solvent prepared from ethylene oxide and ethylene glycol.
Triethylene glycol is a clear, colorless, viscous, stable liquid with a slightly sweetish odor. Soluble in water; immiscible with benzene, toluene, and gasoline. Combustible. Because it has two ether and two hydroxyl groups its chemical properties are closety related to ethers and primary alcohols. It is a good solvent for gums, resins, nitrocellulose, steam-set printing inks and wood stains. With a low vapor pressure and a high boiling point, its uses and properties are similar to those of ethylene glycol and diethylene glycol. Because it is an efficient hygroscopic agent it serves as a liquid desiccant for removing water from natural gas. It is also used in air conditioning systems designed to dehumidify air.
