Triethylene glycol (TEG) belongs to the family of Glycols, a class of organic chemicals that are characterized by having two separate hydroxyl groups. In addition, TEG has two ether linkages, which contribute to its high water solubility, hygroscopicity, solvent properties and reactivity with many organic compounds.
It is derived as a co product in the manufacture of Ethylene Glycols from Ethylene Oxide and from “on purpose” production using Ethylene Glycol.
TEG is a transparent, colorless to pale yellow, low volatility, moderate viscosity, water soluble liquid. Under normal conditions, there is no detectable odor; under high vapor concentration, a slightly sweet odor may be detected.
End-users for TEG are numerous with uses as solvents, plasticizer, and freezing point depression. We have proudly served the oil and gas industry for decades.
