“…More recent measurements by Mohsen-Nia et al using the cloud point method with a flat capacitor for the ternary system (water + propionic acid + dichloromethane) show that the application of an electric field on the order of 10 -8 V/Å increases the two phase region. 34 Purely theoretical work most often predicts that the application of an electric field causes an increase in the critical temperature, [35][36][37][38][39] although the recent statistical-mechanical theory of Stepanow and Thurn-Albrecht predicts an increase in the critical temperature for polarizable liquids and a decrease in the critical temperature for polar liquids. 40 However, recall that the theories of Debye and Kleboth 24 and Wirtz and Fuller 29 predict a decrease in the critical temperature, which they do in fact observe experimentally, although there were possible problems with temperature control in their experiments.…”

“…Hegseth and Amara observed an increase in T C of several mK at field strengths on the order of 10 −5 V/Å, with larger increases for larger field strengths. More recent measurements by Mohsen-Nia et al using the cloud point method with a flat capacitor for the ternary system (water + propionic acid + dichloromethane) show that the application of an electric field on the order of 10 −8 V/Å increases the two phase region …”

Gibbs ensemble Monte Carlo simulations are employed to examine the influence of moderately strong electric fields on the vapor-liquid coexistence curves and on structural and energetic properties of the saturated phases of water, methanol, and dimethyl ether. The application of an electric field of 0.1 V/A increases the critical temperature and normal boiling point by approximately 3% compared to the zero field case for all three compounds, whereas the critical density is found to decrease by 1% for methanol and dimethly ether and by 3% for water. For the special case of an electric field applied in only the liquid phase, these effects are magnified with a 4% increase in T(C) and a 13% decrease in rho(C). For the case of an electric field in only the vapor phase, the opposite effect is seen with a 4% decrease in T(C) and a 12% increase in rho(C). Structural analysis shows very little change in the radial distribution functions, but greatly increased orientational ordering with the application of an electric field. The orientational ordering effect is stronger in the liquid phase than in the vapor phase. An examination of the energetics reveals that, in the presence of an electric field, the interactions with the first and second solvation shells become less favorable but these are outweighed by a larger increase in the favorable long-range interactions with more distant molecules and the field.

“…Therefore, the application of them to the phase separation in the solvent extraction process has been considered from the technical and economical viewpoints. For studying this purpose, the effect of the applied different fields on phase behavior of several ternary systems has been obtained and reported [43][44][45][46][47][48]. There are a number of effective potentials for future research to evaluate the effects of the magnetic, electromagnetic, and ultrasonic fields on the extraction of phosphoric acid from aqueous mixtures.…”

Various ternary and quaternary liquid-liquid phase equilibrium data for water þ phosphoric acid þ solvent(s) have been reported. Salting-out, solvent, and temperature effects on the binodal curve and the tie lines have been highlighted and the capability of solvents with different functional groups to extract phosphoric acid from water has been compared. Studying of influence of magnetic, electromagnetic, and ultrasonic fields on the separation factors and distribution coefficients of aqueous phosphoric acid mixtures has been proposed. Moreover, a summary of the optimized binary interaction values, which resulted from non-random two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) thermodynamic models using genetic algorithm (GA), bee algorithm (BA), and simulated annealing (SA), has been presented. Group method of data handling (GMDH) and linear solvation energy relationship (LSER) methods for the correlation of experimental liquid-liquid equilibrium (LLE) data have been used.
