Ethyl Glyme (CAS: 629-14-1)
Ethylene glycol dimethyl ether CH3CH2OCH2CH2OCH2CH3
An aprotic glycol diether with active solvency and formulating versatility Ethyl diglyme is unique among ethylene oxide based solvents in that it is aprotic (no hydroxyl functionality). As a result it is a relatively inert solvent with outstanding stability at high pH. The lmoderate boiling point allows for easy separation from reaction mixtures and recovery. Used as a solvent for Organometallic reactions involving reductions, alkylations, Grignard and in reactions involving alkali metals. Take advantage of its partial water solubility for purification.
