Biobutanol and n-propanol recovery using a low density phosphonium based ionic liquid at T=298.15K and p=1atm

Liquid–liquid equilibria for ternary mixtures of water + 2-propanol + 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquids at 298.15 K

“…For example, H Ghanadzadeh Gilani et al [7] investigated ternary equilibrium data of mixtures consisting of 2-butanol, water, and heavy alcohols at T = 298.15 K. Amparo Cháfer et al [14] presented LLE data of systems 4-methyl-2-pentanone + water + 1-propanol, 2-propanol. Comparing with the organic solvent, ionic liquids (ILs) have been causing researchers' attention in the application of LLE containing alcohols and water [2,19,[22][23][24][25][26][27][28][29][30][31][32][33][34] for their advantages, such as negligible vapor pressure, non-flammability, and tunable physiochemical properties [35]. For example, Catarina M. S. S.…”

“…Dharamashi Rabari et al [34] obtained successful recovery of butanol and propanol from aqueous solution by introducing phosphonium-based ILs that has density lower than water. Few scholars have concentrated on the LLE of water + 2-propanol + ILs comparing with the ternary systems of water + 1-butanol + ILs that show the Treybal's Type [26,27,29].…”

“…The experimental LLE data for the ternary systems have been correlated by the NRTL and UNIQUAC models ( Table 2) which have provided adequate correlation for ternary systems containing ILs [34,49,51]. The molecular volume structure parameter r and the molecular surface area parameters q, q' of ILs in UNIQUAC model calculated are listed in Table 3.…”

Mutual solubilities between water and non-aromatic sulfonium-, ammonium- and phosphonium-hydrophobic ionic liquids

“…[2][3][4][5][6] With regard to their potential application in separation processes, there is considerable interest in replacing conventional volatile organic solvents with ILs. In particular, it has been reported that ILs have a high capacity for the separation of metal ions, 7,8 organic compounds, [9][10][11] and biofuels [12][13][14] from aqueous solution. For instance, for the latter application, Simoni et al 13 have shown that hydrophobic ILs are capable of extracting 1-butanol from aqueous solutions with a selectivity up to 300-fold.…”

Ferrocene redox in trihexyl(tetradecyl)phosphonium bis-2,4,4-(trimethylpentyl) phosphinate (Cyphos IL-104)/ethanol at glassy carbon and platinum working electrodes

“…A supported liquid membrane based on Cyphos IL-104 has been used for boron removal from aqueous media [8]. There has been interest in using Cyphos IL 104 for the extraction of organic compounds such as lactic acid [10,13], 1-propanol and 1-butanol [11], ethanol (EtOH) [12], mono ethylene glycol [13], and L-malic and succinic acids [14]. It is considered to have application as a lubricant when used as an oil additive [14], a dispersant of conductive silver pastes for photovoltaic applications [16], a new compatibilizer for thermoplastic blends [17], in the extractive desulfurization of liquid fuels [18], and in the synthesis of Pd nanocrystals [19].…”
