Five ionic liquids, namely, 1-alkyl-3-methylimidazolium hydrogen sulfate ([C_nMIm]HSO₄; alkyl = Et, Bu, hexyl, octyl) were synthesized and characterized by NMR and FT-IR spectra. The phys. properties including solubility, d., viscosity, thermostability, conductivity, pK_a were measured. The results showed that the alkyl chain length had the most dramatic effect on phys. properties. The d. of [CnMIm] HSO₄ decreased with increasing length of alkyl in imidazole. Viscosities were correlated with the length of the alkyl chain in imidazole and the viscosity of [C₄MIm]HSO₄ was the lowest( 16.359*10^-3Pa路s). Because of the effect of hydrogen bonds and Van Der Waals forces, the pK_a of [C₆MIm]HSO₄ was the lowest (0.695). The limiting molar conductivity of [CnMIm]HSPO₄ was greater than that of KCl and the limiting molar conductivity of [C₄MIm]HSO₄ had the highest value. Solubility depended on the polarity of solvents and the compounds were easily dissolved in higher polarity solvents.

And the article was included in Journal of Physical Chemistry A in 2010.COA of Formula: C10H20N2O4S The following contents are mentioned in the article:

The acidic room-temperature ionic liquid 1-hexyl-3-methylimidazolium hydrogen sulfate has recently been identified to have beneficial properties for practical applications in catalysis and electrochem. In the present work, the conformational isomerism of this ionic liquid is studied by means of d. functional theory calculations and experiments in terms of IR absorption and Raman scattering spectroscopy. For the hydrogen sulfate anion, the trans conformer is found to be the favored isomer in the ionic liquid For the 1-hexyl-3-methylimidazolium cation, three different low-energy conformations were obtained, differing only in the orientation of the hexyl chain. The comparison of vibrational frequencies with IR and Raman data showed good agreement for all three conformations, indicating their presence in the ionic liquid Beyond revealing the conformational information, the exptl. spectra indicate strong interionic interactions. Vibrations of sulfuric acid could be observed, indicating possible proton transfer from the cation to the anion. This is further supported by the appearance of modes around 2000 cm^-1 in the IR spectrum, which could tentatively be assigned to C2-H stretching vibrations red-shifted as a result of strong interionic hydrogen bonds as a prerequisite of proton transfer.

Cellulose-based nanocomposites have gained much attention due to their remarkable biol. properties such as biodegradability, biocompatibility, and low toxicity. In this research work, 1-h-3-methylimidazolium hydrogen sulfate ionic liquid was employed as an efficient solvent for preparation of cellulosic Ag-nanocomposites (CRC/AgNPs composite) from Neem plant. Ionic liquid plays a dual role in obtaining cellulose-rich compound (CRC; removing lignin and hemicellulose components) and plant’s extract (phenolic compounds such as flavonoids, tannins, etc.) that reduces the AgNO₃ into AgNPs for preparation of CRC/AgNPs composite. The prepared CRC/AgNPs composite was characterized using XRD, FTIR and SEM techniques. The XRD and FTIR spectral anal. showed the characteristic peaks assigned to cellulosic constituent and AgNPs. SEM anal. revealed the particles in the range from 26 to 56 nm. The CRC/AgNPs composite was evaluated for its antibacterial and mech. properties. The antibacterial activity against S. aureus and E. coli for CRC/AgNPs composite was observed in comparison to CRC. Cell viability and morphol. were performed on MC3T3-E1 cells which showed no as such toxicity for the prepared CRC/AgNPs composite.
