Description and Uses
Bis (2-methoxyethyl) ether, also known as diglyme, is a linear aliphatic diether widely used as a solvent and present as a clear liquid at room temperature with a mild ether odor. The compound is notknown to occur in nature. It is synthesized from ethylene oxide and methanol in the presence of either acidic or basic catalysts. The reaction is based on the classic Williamson ether synthesis. It can also be produced from diethylene glycol and dimethyl sulfate. In June 2012, ECHA proposed addition of diglyme to the REACH very high concern list.
Bis (2-methoxyethyl) ether, due to being chemically inert and possessing excellent solvent properties, is mainly used as a solvent and an anhydrous reaction medium for organometallic synthesis. It is also used as a solubilizer.
