Description
It is a liquid ether used as an aprotic solvent. It is also known as glyme, monoglyme, dimethyl glycol, ethylene glycol, dimethyl ether, dimethyl cellosolve, and DME. It has the special ability to form chelates thanks to the high flexibility of its chains. Moreover, DME is the molecular model system for the poly(oxyethylene) chain. It is commonly used as a solvent in batteries and in organometallic reaction chemistry since it has higher boiling than diethyl ether and THF.

Application
1. This versatile compound finds its primary application in polymer chemistry, electrochemistry, and boron chemical processes. However, its utility extends further, serving as a valuable component in resins, nitrocellulose solvents, pharmaceutical extraction agents, and even organic synthesis intermediates.
2. It is widely used as a solvent for electrolyte of lithium batteries, polysilicones, oligo- and polysaccharides. It plays an important role in Grignard reactions, Suzuki reactions and Stille couplings in organometallic chemistry and in pharmaceutical synthesis. It is a higher boiling point solvent and is used as an alternative to diethyl ether and tetrahydrofuran. It is used for the etching of synthetic polymers like polytetrafluoroethylene and other fluoropolymers with alkali metal dispersions.
