What are the properties of TEG glycol (CAS 112-27-6)?

What is TEG glycol (CAS 112-27-6)?

TEG glycol also known as triethylene glycol, is a high-performance, colourless, odourless liquid with excellent hygroscopic and solvent properties, and it is widely recognised for its primary application in natural gas dehydration, where it effectively removes water vapour from gas streams. TEG glycol CAS 112-27-6 is also used as a solvent, plasticiser and humectant in various industrial processes.

TEG Molecular Structure: 

TEG's structure, which consists of a chain of two ethylene glycol molecules linked by an ether group, allows it to attract both water and oil. This quality makes TEG an ideal solution for various applications requiring high solubility, moisture absorption, and stability across temperatures.

What are the properties of TEG glycol (CAS 112-27-6)?

Physical Properties:

• Boiling Point: 285 °C (545 °F) - This is relatively high.
• Melting Point: -7 °C (19 °F)
• Density: ~1.125 g/cm³ at 20°C (denser than water).
• Vapor Pressure: Very low (< 0.01 mmHg at 20°C) - meaning it does not evaporate easily.
• Viscosity: Viscous liquid at room temperature.
• Hygroscopicity: Highly hygroscopic - it readily absorbs moisture from the air.
• Solubility: Miscible with water, alcohols, acetone, and many other common organic solvents.

What is Triethylene Glycol tEG Used for?

• Antifreeze
• Coolants
• Chemical intermediates
• Gas dehydration and treatment
• Heat transfer fluids
• Polyester resins
• Solvents
