What is Diglyme?
Description
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.
The Uses of Diglyme
Diethylene glycol dimethyl ether is used as a solvent in organic reactions due to its stability towards higher pH and its high boiling point. It is particularly involved in reactions utilizing organometallic reagents such as Grignard reactions and metal hydride reductions. It is also a solvent for hydroboration reactions with diborane.
