| | Tetraethylene glycol dimethyl ether Usage And Synthesis |
| Chemical Properties | clear liquid | | Uses | Tetraethylene glycol dimethyl ether is used as a solvent.
| | Uses | Solvent. | | Uses | Tetraethylene glycol dimethyl ether is used in lithium-ion battery technology. It is associated with trifluoroethanol and used as a working pair for organic absorption heat pumps. It acts as a solvent for cleaning and degreasing due to its chemical and thermal stability. Moreover, it is suitable solvent for high temperature reactions due its high boiling point. Further, it is used in the selective adsorption of proteins during the promotion of cell adhesion. | | 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 | | Safety Profile | Mildly toxic by ingestion. Experimental reproductive effects. An eye irritant. Many glycol ethers are suspected of having dangerous human reproductive effects. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS | | Purification Methods | Stand the ether over CaH2, LiAlH4 or sodium, and distil it when required.
