Tetraethylene glycol dimethyl ether is used as a solvent.
| [Definition]
ChEBI: Tetraglyme is a polyether. | [General Description]
Tetraethylene glycol dimethyl ether or tetraglyme is an organic aprotic colourless solvent with film forming ability. | [Flammability and Explosibility]
Nonflammable | [reaction suitability]
reagent type: cross-linking reagent
reaction type: click chemistry | [Purification Methods]
Stand the ether over CaH2, LiAlH4 or sodium, and distil it when required. [Beilstein 1 IV 2404.] | [Advantages]
Tetraethylene glycol dimethyl ether (TEGDME) could be used as a bifunctional solvent which serves as both the casting solvent and active component by controlling the residual amount of TEGDME from excessive to appropriate. This method could avoid the negative impact of the residual organic solvent (such as acetonitrile) in polymer electrolytes prepared by the solution-casting method on battery performance. The residual TEGDME serves as a plasticizer in HSE that is beneficial for improving the plasticity and decreasing the crystallinity of PEO so that it can increase the mobility of lithium ions and flexibility of solid electrolytes. TEGDME can also improve the plasticity and interfacial contact[1]. | [Environmental considerations]
Tetraethylene glycol dimethyl ether is a polar, non-aromatic compound. It is nonionic but water-soluble due to its polarity. However, it has been detected in municipal effluents, runoff from fields irrigated with treated wastewater, and wastewaters of two different waste oil refineries Citation[2]. | [References]
