Triethylene glycol, commonly called TEG, is a clear, viscous liquid distinguished by strong moisture absorption, low volatility and a high boiling character. It dissolves in water but is immiscible with hydrocarbons. Used principally as a liquid desiccant in natural gas processing and air dehumidification, it also serves in printing inks, wood stains, plasticizers and hydraulic fluid formulations.

Product Description of Triethylene glycol CAS#112-27-6

Triethylene glycol (TEG) is a clear, viscous, slightly sweet liquid, soluble in water but immiscible with hydrocarbons. A versatile solvent with low volatility and strong hygroscopicity, it is primarily used as a liquid desiccant for natural gas and air conditioning systems.


Product Application of Triethylene glycol CAS#112-27-6

Triethylene glycol (TEG) is a versatile chemical derived from ethylene oxide and ethylene glycol. Its key uses include liquid desiccant (natural gas, CO₂, H₂S, air conditioning), fatty acid gelator, nanoparticle synthesis solvent, plasticizer, hydraulic/brake fluid additive, disinfectant, and component in inks, antifreeze, cleaning products and lubricants.
