“…The nonrandom two-liquid (NRTL) model has gained significant prominence and widespread adoption in the field of liquid–liquid equilibrium analysis, specifically for fitting experimental data relating to binary , and multicomponent systems. ,− This model proves invaluable in cases where a diverse array of compounds is involved, ranging from those exhibiting nonideal interactions to those featuring substantial deviations from ideal behavior, encompassing both polar and nonpolar molecules . Remarkably, its applicability extends to lactate compounds, − including butyl lactate, , while also including partially miscible systems as well as completely miscible mixtures .…”

This work presents the isobaric liquid−liquid equilibrium (LLE) data for the binary mixtures of butyl L-lactate + water and butyl lactate + water, which were measured at 74.6 kPa in the temperature range from 283 to 343 K. The composition of the samples from LLE experiments was determined by gas chromatography using a Shimadzu 2010 plus with a thermal conductivity detector (TCD). The nonrandom two-liquid (NRTL) and universal quasichemical activity coefficient (UNIQUAC) models were applied to correlate the experimental data and to determine the binary interaction parameters. Both models generate data that correlates well with the observed experimental data and the parameter determination was proved to be consistent through topological analysis of the generated G M /RT function, such that the correlations can be applied to the separation process design for the synthesis of n-butyl lactate via reactive distillation.

“…For liquid-liquid extraction, the selection of extractant is of importance, which can significantly affect extraction performance. Usually, organic solvents are considered as extractants in the extraction process, such as esters (Abu Al-Rub and Datta 1999;Zheng et al 2016;Wu et al 2008;Sun et al 2017;Liu et al 2018b), ethers (Swanepoel and Schwarz 2017;Letcher et al 1992), heavy alcohols (Wang and Liu 2012;Xu et al 2016;Gilani et al 2012a, b;Yang et al 2013) and ketones (Cháfer et al 2012(Cháfer et al , 2014. However, the organic solvents have limitations in chemical separation applications due to their volatility, toxicity and flammability, and the organic solvents should be recovered by distillation with more energy consumption.…”

In this work, to separate the azeotrope of isopropanol and water using liquid-liquid extraction, two deep eutectic solvents (DESs) were prepared with methyl trioctyl ammonium chloride and (1-hexanol/1-decanol), which were characterized by 1 H NMR and were adopted as extractants. The liquid-liquid equilibrium data for the mixtures (DESs + isopropanol + water) were determined at 298.15 K and 308.15 K. The distribution ratio (D) and separation factor (S) were obtained to judge the extraction performance for the selected DESs. The calculated values of D and S showed that the separation of the mixture isopropanol and water by the DESs is feasible. In addition, the experimental data were successfully fitted by the NRTL model with the RMSD values less than 0.0080. The parameters of the NRTL model were optimized, which is helpful for the separation design and simulation.

The liquid–liquid equilibrium (LLE) of a ternary system of water (H2O) + 2-propanol + 1-decyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Dmim][NTf2]) ionic liquid was measured in the temperature range from 278.15 to 298.15 K at atmospheric pressure. The distribution coefficient and selectivity were calculated to determine the influence of the temperature on the LLE. The results indicate that a decrease in temperature reduces the solubility of H2O in [Dmim][NTf2] and increases the immiscibility region of the ternary phase diagram. The experimental data were correlated using the nonrandom two liquid and the universal quasichemical models, and the critical properties for [Dmim][NTf2] were determined.
