Functionalized Ionic Liquids and Their Applications

An ionic liquid represented by the structure of the following Formula 1:

• wherein
• (a) R1 and R2 are each independently H, or a C1 to C12 straight-chain alkyl group or branched alkyl group or aryl group,
• (b) m is an integer 1 to 6,
• (c) X is —N(R3)—(CH2)q—OH, wherein R3 is H or C1 to C6 straight-chain or branched alkyl group and q is an integer from 2 to 4, and
• (d) A− is an anion, selected from the group consisting of [BF4]−, [PF6]−, [CH3CO2]−, [HSO4]−, [CF3SO3]−[(CF3SO2)2N]−, [(CF3SO2)3C]−, [SO4]2−, Cl−, Br−, I−, [N(CN)2]−, [(PO4)(C4H9)2]−, [(PO4)(C2H5)2]−, [(PO4)(C6H5)2]−, [CH3CH2OSO3]−, [CH3OCO2]− and amino acid.
