Triethylene Glycol TEG Industrial Grade High Purity Liquid Chemical Material

Triethylene Glycol (CAS:112‑27‑6, molecular formula) is a high‑purity diol‑series organic compound synthesized from ethylene oxide raw material via ring‑opening addition reaction and multi‑stage distillation refining. It appears as colorless transparent viscous liquid, nearly odorless with slight sweet taste, featuring excellent water‑solubility, good compatibility with alcohols, ketones and many organic solvents, low volatility and strong moisture‑absorbing performance. Compared with mono‑ethylene glycol and di‑ethylene glycol, triethylene glycol owns higher boiling point, lower volatility and better thermal stability, not easy to volatilize under medium‑high temperature working conditions. Benefiting from its outstanding moisture‑absorbing capacity, metal ion compatibility, solvency and thermal transfer property, it has become a widely‑applied safe industrial diol material, complying with relevant industrial chemical specifications. Our production adopts continuous distillation purification technology to strictly control moisture, acidity, ash and impurity indicators, stable effective content, widely applied across natural gas dehydration, resin & coating manufacturing, daily chemical formulation, organic synthesis and heat‑transfer fluid fields。

Applications
Natural Gas & Petrochemical Industry (Core Consumption Field): It is the dominant dehydrating absorbent for natural gas and liquefied gas processing. It efficiently absorbs water vapor from gas stream to lower gas dew‑point, prevent pipeline hydrate blockage; the saturated triethylene glycol can be regenerated by heating for cyclic reuse, bringing prominent economic benefits. It is also used as absorption medium for tail‑gas recovery in petrochemical units.
Resin, Coating & Ink Manufacturing: Acts as high‑boiling‑point environment‑friendly solvent, plasticizer and synthetic intermediate for polyester, polyurethane and alkyd resin production. It improves resin flexibility, weather resistance and film‑forming performance. In paint, adhesive and printing ink systems, it optimizes leveling property and adhesive force, slows solvent volatilization rate to avoid film surface defects caused by too‑fast drying.
Daily Chemical & Cosmetic Formulation: Serves as humectant, solvent and viscosity regulator for skin‑care products, hair‑care formulations and fragrance raw materials. Its mild hygroscopic property helps maintain system moisture balance, stabilizes cosmetic emulsion system and improves raw‑material dissolving performance for fragrance and functional additives.
Heat‑transfer Medium & Antifreeze System: Used as high‑temperature resistant heat‑transfer fluid for closed‑loop circulating thermal equipment; mixed with water to prepare antifreeze & anti‑corrosion liquid for special industrial cooling loops, featuring low‑freezing‑point and anti‑corrosion performance for metal pipeline.
Fine Chemical and Other Fields: Key raw material for synthesizing triethylene glycol ether, ester derivatives; also applied as extraction agent, organic reaction solvent and gas‑chromatography stationary phase in organic chemical synthesis process.
