Phase equilibria study of the binary systems (ionic liquid+thiophene): Desulphurization process

Ionic liquids on desulfurization of fuel oils

“…Following this line, Gao et al [53,54] perform several extraction experiments with alkyl-and alkylmethyl-pyridinium-based ionic liquids, but best results were found for [alkyl-dmpy] + ionic liquids. With these cations, ethanoate and thiocyanate anions gave the best extraction performance (consistent with Domanska et al [55] conclusions in their equilibrium studies). In this way, these more benign and cheaper anions could be used as alternative to the perfluorinated and tetrafluoborate ones.…”

Modeling ionic liquids and the solubility of gases in them: Recent advances and perspectives

“…Lattice models [133,134], [137], [140,141] [ 133,134], [137], [140,141] [ 134,135], [137], [140] [ 134,135], [138] Solubility of CO2 and CF3H at high pressure up to 100 [87], [105] [68], [87], [105,106] [ 68,69], [98] SLE, LLE and VLE of binary mixtures between several pyridiniums with alcohols and thiophene. Activity coefficients of quaternary ammonium salts in water.…”

Correlation of VLE Data for the Thiophene + [bmim][BF4], +[bmim][PF6] Binaries Utilized for the Regeneration of Ionic Liquids

“…(1). In the correlation procedures, three NRTL parameters, α 12 , τ 12 and τ 21 are determined for optimizing the following objective function:…”

“…One particular application of interest is thiophene removal from liquid fuels; hence ternary liquid-liquid equilibria (LLE) data for thiophene + hydrocarbon + IL systems have been extensively reported [2][3][4][5][6][7][8][9]. In addition, binary LLE data [10] and solid-liquid equilibrium (SLE) data [11,12] have been also reported. However, only Huo et al [13] have reported vapor-liquid equilibrium (VLE) data for thiophene + IL binaries.…”
