Equilibrium of Aqueous Propionic Acid with Trioctylamine in Dodecane

Modeling the liquid–liquid equilibrium for the recovery of carboxylic acids from aqueous solutions

“…A literature study provided a lot of experimental data on the partitioning of a variety of carboxylic acids, e.g., acetic acid [2][3][4][8][9][10][11][12][13][14], oxalic acid [15][16][17][18], citric acid [19][20][21][22][23][24][25][26][27][28], lactic acid [3,4,23,27,[29][30][31], succinic acid [3,16,27,32], tartaric acid [27,33,34] and malic acid [23,33,34]. These investigations were carried out for a variety of single organic solvents such as alkanes (from hexane and cyclohexane to dodecane [14,16,30,35]; aromatics, e.g., benzene, toluene and xylenes [16,18,[26][27]…”

Experimental and Correlated Liquid–Liquid Equilibrium Data for (Water + Propionic Acid + Ethylbenzene or Benzyl Benzoate) Ternary Systems

“…It is a clear, corrosive, and water-soluble oily liquid with an unpleasant pungent odor, which can be produced by chemical synthetic or fermentation methods . It forms an azeotrope (a constant boiling mixture) with water (17.8 wt % propionic acid, 82.2 wt % water) with a minimum boiling temperature of 373.0 K (at 760 mmHg) . Consequently, separation of this acid from aqueous solutions is an economically and environmentally crucial issue.…”

“…4 It forms an azeotrope (a constant boiling mixture) with water (17.8 wt % propionic acid, 82.2 wt % water) with a minimum boiling temperature of 373.0 K (at 760 mmHg). 5 Consequently, separation of this acid from aqueous solutions is an economically and environmentally crucial issue. In the earliest investigations, several authors have reported many LLE data on systems containing water, PA, and organic solvents from different chemical categories.…”

Effects of external electromagnetic field on binodal curve of (water+propionic acid+dichloromethane) ternary system

“…There are various papers that report experimental LLE data for the (water + propionic acid + organic solvents) ternary system in the literature [3,7,16,[17][18][19][20][21][22][23][24]. In our previous work, we presented the LLE results for the (water + propionic acid + dichloromethane) ternary system at 91.3 kPa and T = (277.15, 284.15, and 294.15) K. In this work, the effect of the applied EMFs with different frequencies and amplitudes of voltage on the binodal curve data of (water + propionic acid + dichloromethane) ternary system at 91.3 kPa and T = (284.15, and 294.15) K are obtained and reported.…”
