Liquid-liquid equilibrium constant for acetic acid in an olive oil-epoxidized olive oil-acetic acid-hydrogen peroxide-water system [PDF]

Hemijska Industrija, 2016
The liquid-liquid equilibrium constant for acetic acid in a quinary system olive oil-epoxidized olive oil-acetic acid-hydrogen peroxide-water was experimentally determined for temperatures and component ratios relevant for in situ epoxidation of

Phase behavior of water-menthol based deep eutectic solvent-dodecane system

Chemical Thermodynamics and Thermal Analysis, 2021
In the current work, two menthol-based hydrophobic deep eutectic solvents (DESs) have been synthesized to extract dodecane from water-dodecane emulsion at 298 K and atmospheric pressure.

Assessing Water Solubility of Ester‐Based Oils and Unravelling Their Mechanisms by a Quantitative Model

High Voltage, EarlyView.
ABSTRACT Moisture is a sensitive issue for transformer oils, as it adversely affects the stability of insulation papers and dielectric strength of the oils. However, the lack of a quantitative model makes it challenging to evaluate the water solubility of ester‐based oils, which is an undesirable restriction for developing novel ester‐based oils ...

Application of the mass-based UNIQUAC model to membrane systems: A critical revision [PDF]

The Journal of Chemical Thermodynamics, 2012
The UNIQUAC model is very suitable in describing (liquid + liquid) as well as (vapor + liquid) equilibrium for a wide range of systems. It can be extended to (solvent + polymer) systems for describing sorption equilibria. The original model is expressed in molar-based terms, but requires knowledge of structural parameters and molar masses of all ...

Understanding Water Activity in Deep Eutectic Solvents: Experimental Screening, Thermodynamic Modeling, and QSAR Predictions

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
Water activity (aw) was measured in eight DESs (10–90 wt% water). Strong DES–water interactions persist to ∼50 wt%, after which structure collapses toward aqueous‐like behavior. Redlich–Kister, Wilson, and COSMO‐RS models showed limited performance, whereas QSAR modeling using COSMOtherm‐derived σ‐profile descriptors significantly improved aw ...

Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 487-507, March/April 2026.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Screen ammonium‐based deep eutectic solvents for CO2 capture: Extended UNIFAC‐DES, calibrated COSMO‐RS, and experiment

AIChE Journal, Volume 72, Issue 2, February 2026.
Abstract CO2 solubility in deep eutectic solvent (DES) is a critical property to indicate the competence of using DESs for carbon capture. This work presents a systematic screening framework with computational and experimental procedures to identify the promising ammonium‐based DESs for CO2 absorption.

UNIQUAC activity coefficient model for the systems of 1-propanol + water and 2-propanol + water [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2005
Predictions of vapor liquid equilibria and azeotrope conditions of binary systems of 1-propanol+ water and 2-propanol+water at 30, 60, and 100 kPa were conducted in this work.
