1,2-Dimethoxyethane is an excellent inert aprotic polar solvent, suitable media for a number of chemical reactions. It forms chelate complexes with metal cations and acts as a bidentate neutral ligand. It possess a low toxicity relative to its corresponding glycol mono-ether (methyl cellosolve).

                               The usages of 1,2-Dimethoxyethane

1,2-Dimethoxyethane is also known as glyme, monoglyme, dimethyl glycol, ethylene glycol
dimethyl ether, dimethyl cellosolve, and DME, a clear, colorless, volatile, flammable liquid. It is
fully miscible with water, methanol, ethanol, diethyl ether, acetone, tetrahydrofuran, benzene,
toluene and many others. Soluble in aliphatic hydrocarbons. 1,2-Dimethoxyethane forms
azeotropes with water , ethanol , chloroform , n-hexane. The Molecular Formula is C4H10O2,
Molecular Weight is 90.12 and CAS NO is 110-71-4.

1,2-Dimethoxyethane exhibits the most typical chemical properties ethers. It is stable both in
acidic and alkali media, but like other ethers it can be oxidized on air to form dangerous explosive
peroxides. DME peroxides are higher boiling and are contact explosives when dry. It should never
be distilled to dryness, as the risk of explosion increases dramatically.

1,2-Dimethoxyethane is an excellent inert aprotic polar solvent, suitable media for a number of
chemical reactions. It forms chelate complexes with metal cations and acts as a bidentate neutral
ligand. It possess a low toxicity relative to its corresponding glycol mono-ether (methyl
cellosolve).

Dimethoxyethane is often used as a higher boiling alternative to diethyl ether and THF.
Dimethoxyethane forms chelate complexes with cations and acts as a bidentate ligand. It is
therefore often used in organometallic chemistry like Grignard reactions, hydride reductions, and
palladium-catalyzed reactions like Suzuki reactions and Stille couplings.

Dimethoxyethane is also a good solvent for oligo- and polysaccharides.The lowest energy form of
dimethoxyethane in the gas phase is the gauche, rather than the anti conformer.Together with a
high-permittivity chemical (e.g. propylene carbonate), dimethoxyethane is used as the
low-viscosity component of the solvent for electrolytes of lithium batteries.

We can also use,2-Dimethoxyethane as a higher boiling alternative to diethyl ether and
tetrahydrofuran as an aprotic neutral polar solvent, it is used for chemical reactions. It is widely
used in organometallic chemistry as a media for Grignard, Suzuki, Heck and other reactions. It is a
good solvent for nucleophilic substitutions, Simmons-Smith reaction (addition of carbene to
double bond);

The other usages of 1,2-Dimethoxyethane are:
as a solvent for oligo- and polysaccharides;
as a low-viscosity component of the solvent for electrolytes of lithium batteries;
for etching of PTFE and other fluoropolymers with alkali metal dispersions;
as a solvent for polysilicones;
as a reacrion media in pharmaceutical syntheses;
as an entrainer;

1,2-Dimethoxyethane (CAS Number 110-71-4) is a stable diether used primarily as an industrial
solvent, process aid and as a component of lithium batteries.
