No.CAS：112-27-6

Triethylene Glycol (TEG) is a high-boiling, hygroscopic diol. It is primarily used as a dehydrating agent for industrial gases such as natural gas and refinery gas (TEG dehydration process), as a liquid desiccant in air conditioning systems, as an intermediate in the production of polyurethane (PU) and polyester resins, and also as a specialty solvent, plasticizer, and humectant for cosmetics and personal care products.

Description

Triethylene Glycol (commonly abbreviated as TEG, CAS No.: 112-27-6) is a linear oligomer of ethylene glycol and an important high-boiling-point polyol. Its most prominent industrial application is as a highly efficient dehydrating agent for industrial gases such as natural gas, refinery gas, and syngas. Through the “TEG Dehydration Unit,” it significantly reduces the water dew point of gases to meet pipeline transmission and subsequent processing requirements, a critical purification step in the oil and gas industry. Due to its high boiling point, low vapor pressure, and strong hygroscopicity, it is also used as a liquid desiccant in air conditioning systems and compressed air systems. In the chemical industry, TEG can serve as an intermediate or reactant in the production of polyurethane elastomers, unsaturated polyester resins, plasticizers, and surfactants. Furthermore, its excellent solvency, low toxicity, and mild properties enable its use in specialty solvents, ink carriers, and cosmetics/personal care products (as a humectant). Our product is industrial-grade Triethylene Glycol, manufactured in Shandong, China, using the mature ethylene oxide hydration process. It has a purity of ≥99.0%, exhibits a light color, and contains low levels of moisture, ethylene glycol, diethylene glycol, and other impurities, ensuring stable and reliable quality. This product is a combustible liquid with a relatively high flash point; however, it should still be kept away from ignition sources during operation. Due to its strong hygroscopicity, it must be stored in tightly sealed containers to prevent moisture absorption and degradation. Standard industrial handling requires the use of appropriate protective gloves and goggles.
