(Liquid+liquid) equilibria of ternary and quaternary systems containing n-hexane, toluene, m-xylene, propanol, sulfolane, and water at T=303.15K

Removal of aromatic hydrocarbons from hydrocarbon mixture using glycols at 303.15 K and 333.15 K and atmospheric pressure: Experimental and calculated data by NRTL and UNIQUAC models

“…1 shows tie-lines data for hexane + toluene + sulfolane system that has been used for validation procedure. It can be observed that our data are very similar with those obtained by Mohsen-Nia and Paikar [52], presenting the same tendency. This is an indication that the methodology proposed in this work is reproducible.…”

“…Hexane + toluene + sulfolane data (at T = 303.15 K and atmospheric pressure) obtained by Mohsen-Nia and Paikar [52] was used for validation of experimental methodology by using titration and densitometry for quantification of the phases in equilibrium.…”

“…A vast number of papers presenting liquid-liquid equilibrium data of systems including aliphatics + aromatics + sulfolane [6,[28][29][30][31][32] have been published in the literature. Nevertheless, only few data of systems containing aliphatics + aromatics + glycols [43][44][45][46][47][48] is available.…”

Liquid–liquid equilibrium (LLE) data for ternary mixtures of {aliphatic+p-xylene+[EMpy][ESO4]} at T=313.15K

“…The latter approach is the most common separation technique recently employed in petrochemical industries [3]. Despite its broad application, the toxic and volatile nature of the employed solvents such as sulfolane [1,[5][6][7][8][9][10][11], glycols [12,13] and propylene carbonate [14] as well as the high cost of solvent recovery, makes researchers to seek for other possible solvents. One of the potential candidates to supersede conventional organic solvents is ionic liquid.…”

Purification of Phosphoric Acid by Liquid‐Liquid Equilibrium

“…Phosphoric Acid Industry -Problems and Solutionsthe mixtures with a mixed solvent has become the turning point topic of the chemistry investigations in recent years [11,[35][36][37][38][39][40][41][42]. As an illustration, Figure 3 compares distribution coefficients of phosphoric acid for three quaternary systems of (water þ phosphoric acid þ mixed solvent (25% DCM þ 75%DCE)or(50%DCMþ 50% DCE) or (75% DCM þ 25% DCE)) [11].…”
