Abstract Deep eutectic solvents (DESs) are low-freezing mixtures formed by hydrogen bond donor (HBD) and acceptor (HBA). The change of HBA and HBD type or their ratio gives rise to a variation of the formed DES structure and properties. Such designable features make DESs meet the specific separation requirement for various systems. This work overviews the applications of DESs in three typical hard-to-separate liquid systems classified based on the solute polarity, namely non-polar solute, mildly...

Abstract null null For long-chain ester formation, reactive extraction intensified by a bifunctional solvent is a proper process concept as the product ester is usually not soluble in water. To screen a bifunctional ionic liquid (IL), both extraction performance and catalytic activity are considered, taking esterification of methanol and heptanoic acid as example. Based on solute-in-IL infinite dilution activity coefficient generated from DNN-based recommender system, infinite dilution selectivi...

Abstract null null Glyceryl monolaurate (GML), as one of widely used industrial chemicals, can be synthesized via Fischer esterification of lauric acid (LA) and glycerol (GL). In this work, we screened boric acid-based deep eutectic solvent (DES) formed from tetrapropylammonium bromide (TPAB) and boric acid to intensify the selective Fischer esterification through conductor-like screening model for realistic solvents (COSMO-RS) theory. The solid liquid equilibrium (SLE) phase behavior, hydrogen ...

Abstract The undesirable greenhouse gas CO2 is chemically also a sustainable carbon resource to synthesize value-added products. Herein we report a two-step strategy for the transformation of CO2 into dialkyl carbonates under ambient pressure and temperature. CO2 is initially captured and activated in 1-alkyl-3-methylimidazolium ionic liquids ([CmC1Im][An], m = 2, 4; An = [HCO3]−, [OAc]−, [Triz]−), forming the adducts of N-heterocyclic carbene (CmC1Im–CO2) and being loaded up to 26.9 wt%; the in...

Abstract null null Separation of terpenoids from terpenes in citrus essential oils (CEOs) downstream processing is essential for practical applications. In this work, 19 deep eutectic solvents (DESs), formed by combining quaternary ammonium salts as hydrogen bond acceptors (HBAs) with alkanediols, glycols, and monocarboxylic acids as hydrogen bond donors (HBDs), were utilized to evaluate their performance in extractive deterpenation of model CEOs. The effects of HBA and HBD structures, including...

Bronsted acidic deep eutectic solvent (DES) formed from 1:2 mole ratio of imidazole (Im) and p-toluenesulfonic acid (PTSA) [Im:2PTSA] was applied for the first time to synthesize 4-phenyl-1,3-dioxa...

Abstract Molecular dynamics simulations with the combination of FT-IR and 1H NMR spectra were carried out to study the mechanism of tuned extractive desulfurization by aqueous tetrabutylphosphonium bromide (TBPB). The intermolecular interaction and microstructure of TBPB with water and the sulfur compound dibenzothiophene (DBT) were investigated. Both the spectra and MD simulation results indicated that TBPB with a small amount of water has strong CH–π interaction between TBP+ cation and dibenzo...

Abstract Capture of CO2 with high efficiency is essential to tackle the global warming issue that has aroused widespread attention. Herein we employed the halogen-free deep eutectic solvents (DESs) consisting of imidazole (Im) and p-toluenesulfonic acid (PTSA) to absorb CO2. The CO2 solubility in [3Im:PTSA], [3.5Im:PTSA], and [4Im:PTSA] is measured in the range of temperature from 303.15 to 333.15 K and pressure from 110 to 1500 kPa. Henry's constants of Hx and Hm and thermodynamic properties of...
