TEG (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 TEG (Triethylene glycol) has two ether and two hydroxyl groups its chemical properties are closety related to ethers and primary alcohols.
TEG (Triethylene glycol) 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, TEG (Triethylene glycol)'s uses and properties are similar to those of ethylene glycol and diethylene glycol.
Because TEG (Triethylene glycol) is an efficient hygroscopic agent it serves as a liquid desiccant for removing water from natural gas.
