What is triethylene glycol?


Triethylene glycol also known as triethylene glycol, triethylene glycol, triethylene glycol diethylene glycol. Colorless, odorless, hygroscopic, viscous liquid. Miscible with water and ethanol, slightly soluble in ether.

 

 

What is the chemical structure of TEG?

 

Triethylene glycol (TEG) is a linear polyether glycol compound with the molecular formula C₆H₁₄O₄ and the structure HO–CH₂CH₂–O–CH₂CH₂–O–CH₂CH₂–OH. This molecule consists of three ethylene glycol units linked by ether bonds and has two hydroxyl groups at the ends. It is hydrophilic and has a flexible molecular chain, making it an important solvent, intermediate, and component of functional liquid materials.

Main Uses of Triethylene Glycol (TEG)

 

Triethylene glycol (TEG) is a multifunctional additive, primarily used as a solvent, plasticizer, antifreeze, surfactant, and raw material for organic synthesis.

Main uses of TEG:

  • As a solvent: TEG is commonly used in the chemical industry as a solvent to dissolve some water-insoluble organic compounds.
  • As a plasticizer: In the plastics industry, triethylene glycol can improve the flexibility of plastics and is therefore used as a plasticizer.
  • Used as an antifreeze: In the automotive industry, triethylene glycol prevents the cooling system from freezing and is therefore used as an antifreeze.
  • Used as a surfactant: In the surfactant industry, triethylene glycol improves product performance and is therefore used as a surfactant.
  • Used as a raw material in organic synthesis: In the organic synthesis industry, triethylene glycol can be used to prepare various organic compounds and is therefore used as a raw material in organic synthesis.
