Liquid–liquid equilibrium of ternary systems 1-octyl-3-methylimidazolium hexafluorophosphate + aromatic + aliphatic hydrocarbons

Extraction of toluene from aliphatic compounds using an ionic liquid as solvent: Influence of the alkane on the (liquid+liquid) equilibrium

“…In addition to the experimental results, literature data obtained with other ionic liquids [5,9,10,14,15,19] and sulfolane [20][21][22][23] The behaviour of the solute distribution ratio is the opposite: the b values obtained with [EMim] [ESO 4 ] are lower than those obtained in literature for other solvents, although in all cases, b values are less than unity. For this reason, when a separation scheme is designed, it is important to find a compromise between S and b to obtain a big amount of high purity aromatic using the minimum possible amount of ionic liquid.…”

“…From these data, the selectivity and solute distribution ratio were calculated. The values obtained were compared with other published results concerning other ILs [5,9,10,14,15,19], and sulfolane [20][21][22][23]. Moreover, comparing the four systems studied, the influence of the size of the chain length of alkane on the extraction was analysed.…”

“…As documented by Meirdersma et al [2], in 2006 there were only four references concerning (liquid + liquid) equilibria for an aromatic and an aliphatic hydrocarbon with ILs. However, in the last five years the number of researchers interested in this field has increased considerably [2][3][4][5][6][7][8][9][10][11].…”

Application of Genetic Algorithm to the calculation of parameters for NRTL and Two-Suffix Margules models in ternary extraction ionic liquid systems

“…Many researchers have successfully used NRTL model for correlating systems containing ILs with respect to traditional methods based on local optimization, e.g. least square method [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], while there is no data correlation based on the Two-Suffix Margules model.…”

Liquid–liquid equilibrium for the ternary systems water+2-methyl-1-propanol+butyl acetate and water+2-methyl-2-propanol+butyl acetate at (298.15 and 323.15)K

“…Till now, the LLE-data of aqueous-organic mixtures have been investigated by many researchers [4,[8][9][10][11][12][13][14][15][16][17][18]]. 2-Methyl-1-propanol and 2-methyl-2-propanol, which are widely present in a watersoluble solution of fusel oil produced in biomass fermentation process [19,20] and have the same molecular formula with similar physical properties, cannot be separated economically by using traditional distillation method due to the formation of azeotrope.…”
