Description

Description générale

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)].
