TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: There is no solid produced during the process of producing the ionic liquid. The reaction temperature of the step of reacting the compound (Q) with the quaternizing agent is 50-200 degrees C. The process further comprises the step of separating the volatile acid from the ionic liquid. The process is a continuous process. The step of reacting the compound (Q) with the quaternizing agent is conducted in a nonvolatile solvent. At least a portion of the ionic liquid solvent is recycled. At least a portion of the ionic liquid that is produced is used as the ionic liquid solvent in the process. The volatile acid is removed by contacting the ionic liquid with an inert gas stream. The volatile acid is removed by subjecting the ionic liquid to a reduced pressure. Preferred Components: The ionic liquid anion moiety is of formula ((Y1SO2)2N-). The ionic liquid anion is bis(trifluoromethylsulfonyl)imide or bis(fluorosulfonyl) imide. The nonvolatile solvent is an ionic liquid solvent. The ionic liquid solvent is (I).Y1 = F or a fluorohydrocarbon comprising perfluorohydrocarbon, preferably trifluoromethyl. Preferred Definitions:    Q = amine heterocyclic moiety having 3-6C in the ring system, preferably pyrrolidine, imidazole, pyridine or piperidine (all optionally substituted); and    RF = fluorinated ionic liquid anion moiety.    SPECIFIC COMPOUNDS - 1 Disclosed compound (I) is prepared i.e. N-methyl-N-butylpyrrolidinium bis(fluorosulfonyl)imide of formula (Ia).    EXAMPLE - In a three neck round bottom flask, equipped with a stirring bar, an addition funnel and an argon inlet, was placed 50.5 g of N-methyl-N-butylpyrrolidinium bis(fluorosulfonyl)imide at room temperature. To this mixture was added 5.15 g of N-methylpyrrolidine. 8.29 g 1-Bromobutane was placed in the addition funnel. The flask was heated with oil bath to reach the solution temperature to 75 degrees C. 1-Bromobutane was added slowly drop wise over 5 minutes. The mixture was then heated to 85 degrees C for 2 hours and 38 minutes and then cooled to room temperature and was evacuated for 30 minutes at 200 mTorr to produce N-methyl-N-butylpyrrolidinium bromide. 3.09 g of homogeneous liquid (mixture of 20% N-methyl-N-butylpyrrolidinium bromide and 80% N-methyl-N-butylpyrrolidinium bis(fluorosulfonyl)imide) at 85 degrees C was placed in a round bottomed flask with a magnetic stirrer and an argon inlet adaptor and was cooled to room temperature. 500 mg of Bis(fluorosulfonyl) imide was added slowly without dilution in water. The resulting mixture was stirred at room temperature for 20 minutes. Hydrogen bromide that was produced in the reaction was removed at reduced pressure to yield 0.88 g of additional N-methyl-N-butylpyrrolidinium bis(fluorosulfonyl)imide.
