General description
Diethyl ether (DEE) is widely employed as solvent for Grignard synthesis. Its efficacy as solvent for Formalin-ether (F-E) sedimentation technique has been studied. It has been reported as a hydroboration solvent. DEE is a promising compression-ignition fuel and its energy density is much higher than ethanol. It is also one of the components in a blend used in diesel fuel.
Application
Diethyl ether may be employed as solvent for the oxidation of secondary alcohols into ketones. It may be employed as solvent in the preparation of triblock copolymer of PCL-PEG-PCL, acrylated PCL-PEG-PCL and the pentablock copolymer PAE-PCL-PEG-PCL-PAE [PAE = poly(β-amino ester), PEG = poly(ethylene glycol), PCL = poly(ε-caprolactone)].

The concept of this research is using poly(beta-amino ester) (PAE) as a duo-functional group for synthesis of the novel sensitive injectable hydrogel for controlled drug/protein delivery. Firstly, PAE made of 1,4-butanediol diacrylate and 4,4'-trimethylene dipiperidine is used as a pH-sensitive
Diethyl ether (DEE) as a renewable diesel fuel.
