An improved synthesis of fluorine-containing room temperature ionic liquids (FRTILs) is described. Twelve FRTILs are synthesized, in which the fluorinated cations based on N-methyl pyrrolidinium (MPy), 1-methly imidazolium (MIm) and diethylsulfide (DES) a

Eight new strategically designed fluoroether sulfone solvents have been synthesized through different synthetic pathways for potential applications in lithium-sulfur battery electrolytes. The structures of these compounds have been confirmed by 1H-NMR, 13C-NMR and elemental analysis. Several 1,2-dimethoxyethane (DME)-based electrolyte formulations have been prepared with these solvents to derive an electrolyte with good ionic conductivity (>5 mS cm?1 at 25 ℃). The viscosity of these new additives has also been determined as it is directly related to the ionic conductivity. Three of these solvents that contain a trifluoromethyl group displayed acceptable ionic conductivity.
Process for hydroxyalkylation of fluorinated alcohols

, (2008/06/13)
Mono O-hydroxyalkylated derivatives of 1,1-dihydroperfluorinated or 1H,1-alkylperfluorinated alcohols are prepared by reacting the alcohols with alkylene carbonates at a temperature of at least 60° C. in the presence of a one- or two-part catalyst. The catalyst is a nitrogenous base, optionally in combination with a tetraalkylammonium halide. The O-hydroxyalkylated derivatives are useful non-ionic surfactants and emulsifiable compounds for fire extinguishing systems.

A convenient transformation of 1,1-dihydroperfluorinated alcohols into O-hydroxyethyl derivatives (RFCH2OCH2CH2OH) is described in which ethylene carbonate is utilized as the alkylating agent. Tetraalkylammonium iodides and trialkylamines are effective catalysts.
