Introduction to Triethylene Glycol (TEG)
Triethylene Glycol (TEG) is a multifunctional organic compound celebrated for its unparalleled moisture absorption, thermal stability, and chemical resistance. With the chemical formula C₆H₁₄O₄, Triethylene Glycol is a cornerstone in industries ranging from natural gas processing to pharmaceuticals. This article explores TEG’s properties, production methods, industrial applications, and safety protocols, positioning it as an indispensable resource for professionals seeking in-depth insights.
What is Triethylene Glycol (TEG)?
Triethylene Glycol (TEG) is a colorless, odorless, slightly viscous liquid classified under glycols. Synthesized as a byproduct of ethylene oxide hydration, TEG’s low volatility and high boiling point (286.5°C) make it ideal for high-temperature applications. Its hygroscopic nature enables efficient moisture control, solidifying its role in critical industrial processes.
Key Properties of Triethylene Glycol
Triethylene Glycol’s unique characteristics drive its widespread adoption:
- Physical State: Viscous liquid
- Boiling Point: 286.5°C (548°F)
- Freezing Point: −7°C (19°F)
- Solubility: Fully miscible with water and polar solvents
- Hygroscopicity: Exceptional water absorption capacity
- Chemical Stability: Resists oxidation and harsh chemicals
How is Triethylene Glycol Produced?
TEG is manufactured through ethylene oxide hydration, yielding a glycol mixture. Advanced fractional distillation refines the product to meet stringent industrial specifications:
- Purity: ≥99%
- Water Content: <0.1%
- Acidity: <0.02%
This process ensures that TEG meets the demands of high-precision sectors like electronics and pharmaceuticals.
