Tetraethylene Glycol (TTEG)
Tetraethylene Glycol (TTEG)
Tetraethylene Glycol (TTEG) is an organic polyether diol in the ethylene glycol family with the molecular formula C₈H₁₈O₅ and CAS Registry Number 112-60-7. Its molecular structure contains two terminal hydroxyl groups and three ether linkages.
Under normal conditions, tetraethylene glycol is generally a clear, colourless to slightly yellow liquid. Its hydroxyl and ether groups contribute to its polar character and compatibility with water and certain polar solvents. Compared with lower ethylene glycols, TTEG has a higher boiling point and lower volatility, making it suitable for industrial applications that require a high-boiling process medium or chemical intermediate.
Industrial Applications
• Resins and polymers: Used as a chemical intermediate or formulation component in selected resin systems, including certain polyester-related applications.
• Plasticisers and industrial formulations: Used in selected plasticiser and chemical formulations, depending on compatibility requirements and the properties of the final product.
• Industrial solvents: Applied as a process solvent in selected chemical manufacturing operations, including certain ink, dye, and formulation processes.
• Separation and purification processes: May be used as a process solvent or formulation component in selected hydrocarbon purification applications, subject to process-specific requirements.
• Lubricants and textile formulations: Used as an intermediate or formulation component in certain lubricant and textile-related products.
• Chemical intermediate: Its bifunctional molecular structure makes it suitable for consideration in the synthesis of selected glycol derivatives and other speciality chemicals.
