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. [Beilstein 1 IV 2404.]
