Description

General description

Nonafluorobutyl methyl ether (Methyl Nonafluorobutyl Ether, MFE) is an alkyl- fluoroalkyl ether (AFE). AFE is widely employed as a nonflammable solvent. MFE is superior to conventional solvents due to its low viscosity and surface tension.[1]

consists of two inseparable isomers (CF₃)₂CFCF₂OCH₃ and CF₃(CF₂)₃OCH₃ with almost identical properties

Application

Nonafluorobutyl methyl ether (Methyl Nonafluorobutyl Ether, MFE) may be used to compose mixed-solvent electrolytes. Flash point, conductivity and NMR spectra of these solvent mixtures have been investigated.[1]
