Butyl Diglyme
Butyl diglyme, also called diethylene glycol di-n-butyl ether, is a polar aprotic solvent with excellent thermal and chemical stability. Glymes, or glycol diethers, are a widely used family of saturated polyethers for increasing anion reactivity in a given system, thus affecting selectivity and reaction rates.
