Tetraethylene Glycol, also known as TEG or TETG, has the CAS number 112-60-7. It is a colorless to pale straw-colored, viscous liquid that is hygroscopic in nature. This chemical is characterized by its molecular formula C8H18O5, and a molecular weight of 194.23 g/mol .
Tetraethylene Glycol is primarily used as a solvent and heat transfer medium due to its high boiling point. It is also utilized as a humectant, plasticizer, and in the formulation of resins and explosives. Additionally, it finds application in the manufacturing of polyethylene glycols (PEGs) and as a building block in organic synthesis .
This compound has a melting point of approximately -6.2°C and a boiling point of around 327.3°C. Its density at 20°C is between 1.123 and 1.126 g/cm3, and its refractive index ranges from 1.450 to 1.470 at the same temperature . The flash point of Tetraethylene Glycol is 176°C, indicating its flammability .
In terms of safety, Tetraethylene Glycol is mildly toxic with an LD50 value of 34650 mg/kg for rats and 22500 mg/kg for rabbits. It is important to handle it with care, avoiding contact with strong oxidizing agents and alkalis. It is also advisable to store it in a cool, dry place away from heat and open flames
