Sulfonic acids in ionic liquids (ILs) are used as catalysts, electrolytes, and solutions for metal extraction. The sulfonic acid ionization states and the solution acid/base properties are critical for these applications. Methane sulfonic acid (MSA) and camphor sulfonic acid (CSA) are dissolved in several IL solutions with and without bis(trifluoromethanesulfonyl)imine (HTFSI). The solutions demonstrated higher conductivities and lower viscosities. Through calorimetry and temperature-dependent… Expand

TLDR
Results elucidate the complicated ionization and solvation mechanism of HTFSI in BMITFSI solutions and suggest that when the concentration is as high as 1.0 M, a significant amount of TFSI(-) is protonated, most likely at the imide nitrogen. Expand

Ionization condition of lithium ionic liquid electrolytes under the solvation effect of liquid and solid solvents.
TLDR
It is concluded that the dispersed silica is effective to modify the hydrodynamic lithium species to be appropriate for charge transport as reducing the size and anionic charge of Li(TFSI)4(3-) by removing one or two TFSI- anions. Expand

Characterization of the bridged proton structure in HTFSI acid ionic liquid solutions.
TLDR
The proton-sharing mechanism implied by these structures confirms that the TFSI(-) ion can be a proton acceptor and a Brønsted base as well in IL solutions, however, the IL molecular cations such as imidazolium and pyrrolidinium do not contribute significantly to the proton solvation and transportation in the solutions.
