Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

What does the NRTL model look like? Determination of boundaries for different fluid phase equilibrium regions

“…There are several examples of the current relevance of this topic. For instance, the thermodynamic modeling of mixtures with new solvents such as ionic liquids (cataloged as more environmentally friendly solvents due to their low volatilities) that present high selectivity and normally complex equilibrium behaviors, 15–18 with interest also as bio‐solvents and cell disrupting agents 19 Other relevant examples, are the development of new and more sustainable continuous pharmaceutical manufacturing processes, 20 where the optimal design of liquid–liquid extraction cascades is required, the design of advanced distillation process (as extractive distillations), or new CO 2 capture procedures, both using ionic liquids 21,22 …”

γ-Valerolactone as a Green Solvent for Extracting Carboxylic Acids and Alcohols from n-Tetradecane: Equilibrium Data for Model Systems at 298.15 K

“…The sigma­(σ)-profile of components might also help understand the differences in phase equilibrium behavior regarding the molecule sizes and organic functions. , This profile represents the probability distribution of the surface-charge density of a molecule and provides information on molecule polarity and its ability to accept or donate hydrogen bonds. The VT-2005 Sigma Profile Database , contained the σ-profile of all chemicals used in this work ( n -tetradecane, GVL, propanoic acid, pentanoic acid, 1-propanol, 1-butanol, and 1-pentanol) and of other oxygenated solutesnamely, butanoic acid, hexanoic acid, butanal, pentanal, propanone, and 2-butanonefrom previous works from the literature, which also studied LLE with n -tetradecane and GVL.…”

COSMO‐RS based ionic liquid screening for the separation of acetonitrile and ethanol azeotropic mixture

“…14 Moreover, it is convenient and easy to obtain a highly efficient IL through design and recombination of anions and cations. 15,16 However, due to the huge database of anions and cations, it is necessary to establish an efficient method to select suitable ILs.…”

“…Ionic liquids (ILs) are innovative solvents due to their excellent properties such as negligible vapor pressure, strong dissolving capacity and good thermal stability . Moreover, it is convenient and easy to obtain a highly efficient IL through design and recombination of anions and cations . However, due to the huge database of anions and cations, it is necessary to establish an efficient method to select suitable ILs.…”
