The salting out of acetonitrile from water in the presence ammonium bicarbonate was studied at atmospheric pressure 4 to 35 °C. coexisting phases were analyzed independently with H1 nuclear magnetic resonance, ion chromatography, calorimetry, and titrations. binodal region described semiempirical functions UNIQUAC thermodynamic model. critical composition ambient temperature is given by 0.02 g/...

liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 k. the studied systems exhibit two types of liquid-liquid equilibrium (lle) behavior. the system consisting of benzyl alcohol displays type-1 lle behavior, while a type-2 behavior is exhibited by the other s...

In this study a simple and general chemical association theory is introduced. The concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. The theory is applied to derive the distribution function of associated species. As a severe test the application of presented theory to the van der Waals mixture model is introduced in order to p...

The performance of three hydrophobic carboxylic acid based Deep Eutectic Solvents were evaluated for the extraction 1-butanol and acetonitrile from aqueous solution. To do so, phase diagrams five ternary systems {[DL-menthol: lauric acid] + water 1-butanol}, capric acetonitrile}, {[TBAMBr:capric 1-butanol} {[TBAMBr: measured at 298.15 K atmospheric pressure. Liquid-liquid equilibria data used t...

Characterization of liquid-liquid equilibrium (LLE) in system containing ionic liquids (ILs) is important in evaluating ILs as candidates for replacing traditional extraction and separation solvents. Though an increasing amount of experimental LLE data is becoming available, comprehensive coverage of ternary liquid-phase behavior via experimental observation is impossible. Therefore, it is impo...
