“…Indeed, it is well known that temperature has a large influence in the phase equilibria with non-ionic surfactants [54,55]. With the few surface active ionic liquids investigated up to date, the effect of temperature in these systems is considered so far almost negligible [23][24][25].…”

“…The highest and the lowest temperatures of the three-liquid-phase-coexisting body correspond to the, respectively, upper (UCST) and lower (LCST) critical solution temperatures. The phase behavior of the ternary (water + alkane + C i E j ) systems has been well examined [6][7][8][9][10][11][12][13].…”

a b s t r a c tThe fish-shaped phase diagram of the ternary system (water + hexadecane + dipropylene glycol n-propyl ether) under atmospheric pressure was performed at constant water/hexadecane mass ratio (1/1). The upper critical solution temperature of the ternary system was determined as 314.00 K. Liquid + liquid equilibria of the system were measured at T = 298.15, 308.15, and 318.15 K under atmospheric pressure. The experimental data of liquid-liquid equilibria were further correlated with the NRTL model.

“…The authors suggest, analyzing the behavior of different alkyl polyglycol ethers (C i E j ), that the monomeric solubility of the surfactant in oil and water might be the key to describe the main features of those microemulsion systems. Several works can be found in literature where compositions of tie-line ends and tie-triangles are determined for ternary systems water-oil-C i E j [11][12][13][14][15][16].…”

The difficulty of achieving a good thermodynamic description of phase equilibria is finding a model that can be extended to a large variety of chemical families and conditions. This problem gets worse in the case of systems containing more than two phases or involving complex compounds such as ionic liquids. However, there are interesting applications that involve multiphasic systems, and the promising features of ionic liquids suggest that they will play an important role in many future processes. In this work, for the first time, the simultaneous correlation of liquid-liquid and liquidliquid-liquid equilibrium data for ternary systems involving ionic liquids has been carried out. To that end, the phase diagram for the system water + [P 6 6 6 14 ][DCA] + hexane has been determined at 298.15 K and 323.15 K and atmospheric pressure. The importance of this system lies in the possibility of using the surface active ionic liquid to improve surfactant enhanced oil recovery methods. With those and previous measurements, thirteen sets of equilibrium data of ternary systems water + ionic liquid + oil have been correlated. The isoactivity equilibrium condition, using the NRTL model, and some pivotal strategies are proposed to correlate these complex systems.Good agreement has been found between experimental and calculated data in all the regions (one triphasic and two biphasic) of the diagrams. The geometric aspects related to the Gibbs energy of mixing function obtained with the model, together with the minor common tangent plane equilibrium condition, are valuable tools to check the consistency of the obtained correlation results.
