Application

Diethyl ether may be employed as a solvent in the following studies:
• Oxidation of secondary alcohols into ketones.
• Preparation of pentablock copolymer PAE-PCL-PEG-PCL-PAE [PAE = poly(β-amino ester), PEG = poly(ethylene glycol), PCL = poly(ε-caprolactone)].
• Preparation of triblock copolymer of PCL-PEG-PCL.
• Preparation of acrylated PCL-PEG-PCL.

General description

Diethyl ether (DEE) is widely employed as solvent for Grignard synthesis. 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. It can also be used as a alternative of diesel fuel.
