Surface active alkyl-imidazolium ionic liquids studied as templates to form vertically oriented pores in silica thin films

Deep Desulfurization of Fuel Diesels Using Alkyl Sulfate and Nitrate Containing Imidazolium as Ionic Liquids

1-ethyl-3-methylimidazolium ethyl sulfate [Etmim][EtSO4 ],1, 3-dimethylimidazolium methyl sulfate [Mmim][MeSO4 ] and 1-octyl-3-methylimidazolium nitrate [Omim][NO3 ] ionic liquids have been used in thermal oxidative desulfurization of model fuel oils consisting of 500 ppm solutions of benzothiophene (BT) and dibenzothiophene (DBT) in dodecane. The efficiency of sulfur removal from BT and DBT so...

Effect of Alkyl Chain Length on Hygroscopicity of Nanoparticles and Thin Films of Imidazolium-Based Ionic Liquids

This work focuses on the interaction of water vapor with ionic liquids (ILs) consisting of [CnMIM] + (n = 2, 4, or 6) cations paired with Cl− or BF4 − anions to examine the effect of alkyl chain length on IL hygroscopicity. Tandem nanodifferential mobility analysis (TDMA) and attenuated total reflectance-Fourier transform infrared (ATRFTIR) spectroscopy were used to study IL nanoparticles and t...

deep desulfurization of fuel diesels using alkyl sulfate and nitrate containing imidazolium as ionic liquids

Aggregation of imidazolium ionic liquids in molecular liquids studied by small-angle neutron scattering and NMR.

The aggregation of two imidazolium-based ionic liquids, 1-ethly-3-methylimidazolium chloride (EMI(+)Cl(-)) and EMI(+) bis-(trifluoromethanesulfonyl)amide (EMI(+)TFSA(-)), in molecular liquids, water, methanol, acetonitrile, and benzene, has been studied by using the small-angle neutron scattering (SANS) technique. The SANS results have shown that the heterogeneity of EMI(+)Cl(-)-acetonitrile mi...

Photo-degradation of Imidazolium Ionic Liquids

Degradation of imidazolium ionic liquid, [bmim][TFSA] and iodide solution of [bmim][TFSA] by UV-laser irradiation has been studied through ground state absorption and transient absorption spectroscopy. We found that excited state [bmim] undergoes degradation efficiently. Introduction Room-temperature ionic liquids are receiving considerable attention because of their remarkable properties, such...
