Characterization of the solubilizing ability of tetraalkylammonium ionic liquids containing a pendant alkyl chain bearing a basic N,N-dimethylamino or N,N-dimethylaminoethoxy functionality

Calculation of Abraham model L-descriptor and standard molar enthalpies of vaporization for linear C7-C14 alkynes from gas chromatographic retention index data

“…The average error and average absolute error between the L values in our database and those calculated based on eqn. (5) are AE = -0.001 and AAE = 0.043, respectively. We do note that the tabulated numerical values of the L solute descriptor based on eqn.…”

“…Through suitable mathematical rearrangement of eqn. (4) L = [(RI/100) -0.967 + 0.458 E]/1.929 (5) one can calculate the L solute descriptors of the remaining 20 C7-C12 alkynes for which RI values are available on a squalane stationary phase. The numerical values of our calculated L solute descriptors are given in the last column of Table 3.…”

“…The model has been shown to provide reasonably accurate predictions for a wide range of solute transfer processes. Specific solute properties, SP, for which predictive expressions have been reported include: the logarithms of the water-to-organic solvent and gas-to-organic solvent partition coefficients, log P and log K, [1][2][3][4][5][6][7] logarithms of blood-to-body tissue/fluid partition coefficients, log Pblood/tissue, [8][9][10][11][12] logarithms of the median lethal concentration of various organic compounds to aquatic organisms, log LC50, [13][14][15][16] enthalpies of solvation of organic vapors and inorganic gases in organic solvents, ∆Hsolv, [17][18][19][20][21][22][23][24][25][26][27] logarithms of molar solubility ratios, [28][29][30][31] isothermal gas chromatographic retention factors and retention indices, RI, Draize eye scores and eye irritation thresholds, [32][33][34] nasal pungency, 32,[35][36][37] skin permeabilities, 38,39 and several other biological response solute properties. 40,41 More recently, the model was successfully extended to the p...…”

Calculation of Abraham model L-descriptor and standard molar enthalpies of vaporization and sublimation for C9 - C26 mono-alkyl alkanes and polymethyl alkanes

“…A complete set of solute descriptors enables one to estimate a large number of physicochemical and thermodynamic properties using published Abraham model correlations. To date we have reported mathematical expressions for predicting log K and log P values for solutes dissolved in both traditional molecular organic solvents [39][40][41][42][43] and ionic liquid solvents, [64][65][66][67][68][69][70][71][72][73] molar solubility ratios, [39][40][41][42][43] blood-to-body tissue/fluid partition coefficients, [74][75][76][77][78] Draize scores and eye irritation thresholds, [79][80][81] enthalpies of solvation, [45][46][47][48][49][50][51][52][53][54][55] lethal median concentrations of organic compounds towards fish and other aquatic organisms, [82][83][84][85] nasal pungency, 79,[86]…”

Extraction of butanol and acetonitrile from aqueous solution using carboxylic acid based deep eutectic solvents

“…Their specific properties enable their use in processes in a large range of temperature and the reduction of atmospheric pollution to almost zero. Promising results were observed with the use of ILs as electrolytes in Lithium-ion batteries [1], as corrosion inhibitors in different industries [2], as components of dye-sensitized solar cells [3] and as solvents for the greenhouse gases capture [4,5] as well as for the extraction of organic or inorganic compounds [6][7][8][9][10]. The high cost of ILs and their toxicity have restricted their industrial applications.…”
