Abstract: The present invention provides a process for producing hydrogen bis(fluorosulfonyl)-imide (HFSI) by fluorination of a liquid hydrogen bis(chlorosulfonyl)imide (HCSI) using a gaseous hydrogen fluoride. In some embodiments, HFSI that is produced is separated from the reaction mixture as a gas and is condensed to collect a liquid HFSI.

Abstract: The present invention provides methods and processes for producing ?-fluoroalkyl ketones from non-fluoro ?-haloalkyl ketones using a fluorohydrogenate compound. In some embodiments, the fluorohydrogenate compound is an ionic liquid. One particular method of the invention utilizes a fluorohydrogenate ionic liquid compound of the formula: Q+[F.(HF)n], wherein Q30 is an onium cation and n is a number from 0 to 3.

Abstract: The present invention provides a process and a method for producing a quaternary ammonium cation in an aqueous solution while reducing or preventing formation of a protonated ammonium cation. In particular, the quaternary ammonium cation is produced by adding a base to an aqueous reaction mixture comprising a tertiary amine compound and an alkylating agent.

Abstract: The present invention provides a method and process for removing at least a portion of a protonated amine compound that is present as an impurity or a contaminant in a quaternary amine compound. The method of invention is particularly useful in producing highly purified ionic liquids that have quaternary amine moiety as the cationic moiety.

Abstract: The present invention provides an N-substituted glycinium (fluorosulfonyl)(trifluoromethylsulfonyl)imide compounds and methods for producing and using the same. In particular, the N-substituted glycinium (fluorosulfonyl)(trifluoromethylsulfonyl)imide compound is of the formula: wherein each of R1, R2 and R3 is independently selected from the group consisting of alkyl, aryl, aralkyl, cycloalkyl, (cycloalkyl)alkyl, heteroaryl, (heteroaryl)alkyl, heterocyclyl, and (heterocyclyl)alkyl; or R1 and R2 together with the nitrogen atom to which they are attached to form a nitrogen-heterocyclyl, or a nitrogen-heteroaryl.

Abstract: The present invention provides a single-phase or homogeneous solution comprising a high concentration of a salt, in particular a lithium salt, in an organic solvent. Such a high salt content in organic solvent is useful in a variety of applications including, but not limited to, in electrical energy storage devices as well as other devices that can benefit from a low-volatility liquid electrolyte.

Abstract: The invention provides a method for producing fluorotrifluoromethylsulfonyl imide (FTFSI) by reacting non-fluorohalogenated trihalomethylsulfonyl imide (XTXSI) with hydrogen fluoride, where each X is independently a nonfluoro-halide, such as Cl, Br, or I.

Abstract: The present invention provides a method for producing ionic liquids without the use of a volatile solvent and/or water. In some embodiments, methods of the invention allow a continuous process for producing ionic liquids.

Abstract: The present invention provides a process for producing a compound comprising a perfluorinated alkyl group moiety from a carbonyl compound. Typically, the process includes contacting a carbonyl compound with a silane compound in the presence of a fluorohydrogenate ionic liquid under conditions sufficient to produce a compound comprising a perfluorinated alkyl group. The silane compound includes a perfluoroalkyl group.
