Descrição

Descrição geral

Diethyl ether (DEE) is widely employed as solvent for Grignard synthesis.[1] Its efficacy as solvent for Formalin-ether (F-E) sedimentation technique has been studied.[2] It has been reported as a hydroboration solvent.[3] 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.[4]

Aplicação

Diethyl ether may be employed as solvent for the oxidation of secondary alcohols into ketones.[3] 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)].[5]
