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. These imidazolium compounds were stable at temperatures lower than 240掳 and behaved as Newtonian fluids.

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.

A hybrid monolith incorporated with graphene oxide (GO) was prepared in the first time with binary green porogens of deep eutectic solvents (DESs) and room temperature ionic liquids (RTILs). GO was modified with 3-(trimethoxysilyl) propylmethacrylate (纬-MPS), and the resultant GO-MPS can be incorporated into poly(methacrylic acid-co-butylmethacrylate-coethylene glycol dimethacrylate) monoliths covalently. A hybrid monolithic column with high permeability and homogeneity can be achieved due to good dispersion of GO-MPS in the green solvents. The GO-MPS incorporated monolith was characterized by TEM, SEM, TGA and nitrogen adsorption tests. The separation of small organic mols. of alkylphenones and alkylbenzenes was used to evaluate the performance of GO-MPS grafted monolith. The GO-MPS grafted monolith displayed the maximum column efficiency of 147,000 plates/m, about twice higher than the GO-free monolith. In addition, all of the retention and selectivity of small mols. of alkylphenones and alkylbenzenes increased due to the addition of GO-MPS. The use of DESs and RTILs is a powerful approach for the preparation of GO incorporated polymer monoliths. The monolith was further applied to the separation of tryptic digests from bovine serum albumin, and the result indicated its potential in the anal. of some complex samples.

Thermodn. parameters at infinite dilution for thirty-one organic solutes in a series of imidazolyl hydrogen sulfate ionic liquids (ILs) were determined by inverse gas chromatog. (IGC). The IGC characterization was carried out at temperatures ranging between 303.15 and 343.15 K for determining the Hildebrand solubility parameter (未₂) as well as the Flory-Huggins interaction parameter (蠂₁₂^{鈭?/sup>), the activity coefficient at infinite dilution (纬₁₂鈭?/sup>), and the thermodn. functions. In addition, based on the 纬₁₂鈭?/sup> results, the selectivity and capacity were directly calculated for two separation problems (hexane/benzene and hexane/thiophene). Under the different effects of the three ILs, it was found that the values of 蠂₁₂鈭?/sup> and 纬₁₂鈭?/sup> were significantly different for the solutes tested, but all the values follow a certain pattern: they increase with temperature or decrease with temperature As the temperature increased, the solubility parameters of the three ILs showed a linear decrease trend. The solubility parameters of the three ionic liquids at room temperature were obtained by extrapolation as 未_{2([BMIM][HSO4])} = 24.15 MPa1/2, 未_{2([HMIM][HSO4])} = 24.10 MPa1/2, and 未_{2([OMIM][HSO4])} = 23.66 MPa1/2.

Aromatics play essential and unique roles in the areas ranging from synthetic chem. to the manufacturing industry. Production of aromatics from biomass is of great fundamental interest and practical importance to ease the burden of fossil resources. This work delineates a one-step route for the synthesis of renewable aromatics from various biobased furanics and dienophiles by acidic ionic liquids at mild conditions. [Bmim]HSO₄ was used as a catalyst and solvent for the direct conversion of 2,5-dimethylfuran and acrylic acid into p-xylene and 2,5-dimethylbenzoic acid; up to 89% aromatic selectivity was achieved at 87% conversion of 2,5-dimethylfuran at room temperature and atm. pressure, and totally 84% selectivity of p-xylene can be obtained with a subsequent decarboxylation reaction. The reaction mechanism study supplemented with isotopic tracing and DFT calculations revealed the lowest-energy pathway for the two main products. Various starting materials were studied for further extensions of the method, and it turned out that electron-donating Me groups on the furan ring played crucial roles on the activation of dehydration and decarboxylation processes. This work provided convenient access to industrial commodity aromatics from fully biomass-derived feedstocks and thus can be regarded more economically and environmentally feasible.

Matured reservoirs are being targeted for enhanced oil recovery (EOR) operations in the hope to recover the residual oil that remains trapped within the porous media. Chem. enhanced oil recovery is one of the successful oil recovery methods which is being employed for the recovery of the residual oil. Many of the conventional chems. fail to perform under high temperature and high saline reservoir conditions. These situations lead to the search for alternate flooding techniques which could efficiently produce the crude oil to the surface. The present work investigates a possible solution for the recovery of trapped crude oil using lactam and imidazolium based ionic liquids (ILs) specifically targeted towards recovery in high saline environment. Initially, the interfacial tension of the crude oil-water system has been investigated using various chem. agents, such as sodium dodecyl sulfate (SDS), and six different ILs at varying high saline concentrations as a function of temperature (283.15-353.15 K). Subsequently, flooding experiments with only polymer, only SDS, only IL, SDS + polymer and IL + polymer at zero and high saline conditions were performed. It was observed that the IL + polymer flood performed very well in both zero and high salinity conditions as compared to all other flooding systems. The present investigation also portrays an intuition on the evaluation of ILs based on their alkyl chain length.
