Diethylene Glycol Diethyl Ether CH3CH2-O-(CH2CH2-O)2-CH2CH3 (CAS: 112-36-7)
A polar aprotic glycol diether with active solvency and formulating versatility. Ethyldiglyme has become a favorite solubilizing agent for water-based inkjet inks. 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 chemical and thermal stability. The moderate high boiling point allows for easy separation of products from reaction mixtures and provides the ability to conduct reactions at high temperature. Used as a solvent for Organometallic reactions involving reductions, alkylations and in reactions involving alkali metals.
