화학적 성질
Tetraethylene glycol is a high-boiling, clear liquid of low volatility. hygroscopic. It is completely miscible with water and a wide variety of organic solvents. insoluble in benzene, toluene, or gasoline. Combustible. For certain aliphatic hydrocarbons, it has a very slight affinity. Tetraethylene glycol is used as a coupling agent for blending water-soluble and water-insoluble compounds in such formulations as lubricants, glues, cork and textile products, etc.
