DME Usage And SynthesisSynthesis1,2-Dimethoxyethane is derived from the reaction of ethylene glycol monomethyl ether with sodium metal and methyl chloride. The ethylene glycol monomethyl ether and the metal sodium were refluxed together until the metal sodium was completely reacted, the temperature was lowered to 45° C., and methyl chloride was introduced. After the reaction is completed, fractional distillation is performed to collect fractions at 84-85.5°C to obtain 1,2-Dimethoxyethane.Chemical PropertiesColorless liquidUsesSolvent commonly employed in organometallic reactions,1 particularly organolithium reactions.2 May also function as a ligand.3UsesMonoglyme is used in the electrolyte solutions for lithium batteries.Uses1,2-Dimethoxyethane 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.
