Ternary Liquid−Liquid Equilibria for the (Methanol + Methylbenzene + Decane) System at Different Temperatures

Abstract

LiquidÀliquid equilibrium (LLE) results for ternary mixtures of {methanol (1) þ methylbenzene (2) þ decane (3)} at different temperatures from (298.15 to 313.15) K are reported. The compositions of the liquid phases at equilibrium were determined by gasÀliquid chromatography. The data were correlated with the NRTL and UNIQUAC equations. Also, the selectivity and distribution coefficient of methanol for the extraction of methylbenzene from decane at different temperatures are compared. The phase diagrams for the ternary mixtures are presented, and the correlated tie line results are compared with the experimental data. The comparison indicates the applicability of the NRTL and UNIQUAC activity coefficient models for LLE calculations on the studied mixtures.

Determination and Correlation of Liquid–Liquid Equilibria Data for Water + Cyclohexanol + (Mesityl Oxide, Toluene, and p-Xylene) Ternary Systems at Different Temperatures

“…In addition, the NRTL model could correlate well with LLE mixtures with the accurate selection of the nonrandomness parameter α ij ; thus, theNRTL model was also considered. In this experiment, the nonrandomness parameters α ij are shown in Table , which considered the polarity of the reagents, advice in the literature, and the improvement in the results. , …”

“…In this experiment, the nonrandomness parameters α ij are shown in Table 5, which considered the polarity of the reagents, advice in the literature, and the improvement in the results. 36,37 The correlation quality through the NRTL and UNIQUAC models were evaluated via the root-mean-square deviation (RMSD), and relevant equation is listed as follows:…”

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

“…The solvents used in aromatics extraction process must present some important features such as considerable polarity, water solubility, affinity for aromatics, density and boiling point higher than the aromatics desired to extract [5]. For this process organic solvents such as sulfolane , dimethylsulfoxide [33], N-methylpyrrolidone [34], N-formylmorpholine [31,[35][36][37][38][39][40][41] and glycols [42][43][44][45][46][47][48] are used.…”
