“…BPA (228.32 cm 3 /mol at 298.15 K) and {[TBAB][Gly]} (143.63 cm 3 /mol at 298.15 K) of the mixtures which can leads to the negative deviation from the ideal behavior. These results are in a good agreement with the reports of Ghaedi et al 48 and Maham et al 52 The attachment of four –CH 3 groups in nitrogen atom increases the electron density of the {[TBAB][Gly]} and it subsequently form H‐bonds with the aq. BPA molecules.…”

“…BPA (x 1 > 0.5) there was a sudden drop in the values for all binary mixtures. Such behavior was observed for the aqueous phosphonium‐based DES reported by Ghaedi et al 48 The binary mixture of aq. BPA + {[TBAB][Gly]} shows highest α values ranging from (6.4068 × 10 −4 K −1 to 6.5991 × 10 −4 K −1 ) at equimolar ratio for 25, 50, 75, and 100 ppm concentrations, respectively.…”

Densities of pure distilled water, tetra butyl ammonium bromide glycerol{[TBAB][Gly]}, and different concentration of aqueous bisphenol A (aq. BPA) (i.e., 25, 50, 75, and 100 ppm) were measured at different temperatures from 293.15–343.15 K. Further, densities of the pseudo binary mixtures of aq. BPA and {[TBAB][Gly]} over the entire mole fraction were measured at different temperatures from 293.15–343.15 K. From these measured density data, the solution thermodynamic properties of the pseudo binary mixtures of aq. BPA and {[TBAB][Gly]} were calculated, and the excess molar volume data were correlated using the Redlich–Kister polynomial equation. Furthermore, the σ‐profiles and σ‐potentials of all the studied species were generated and analyzied in terms of H‐bond donor and/or acceptor at atom and molecular levels. Finally, based on the results of aq. BPA with {[TBAB][Gly]}, tetra butyl ammonium bromide decanoic acid {[TBAB][DA]} and tetra butyl ammonium bromide oleic acid {[TBAB][OA]} based deep eutectic solvents were used for the removal of BPA from the aqueous stream at 298.15 K and 1 atm. This process was characterized in terms of distribution coefficient (D), extraction efficiency (η), and also thermodynamic feasibility of the process at different temperatures.

“…VE is defined by the following Equation:VE=x1M1+x2M2ρmix−x1M1ρ1*−x2M2ρ2* where x1 and x2 are the mole fractions, M1 and M2 are molecular weights, and ρ1*, ρ2* and ρmix are the densities of Component 1, Component 2, and the binary mixture, respectively. Different DES–water binary mixtures show different VE features throughout the entire compositional range [139,140,141,142,143]. For instance, Kuddushi et al suggested that the negative VE<...>…”

Valorization of lignocellulosic biomass and food residues to obtain valuable chemicals is essential to the establishment of a sustainable and biobased economy in the modern world. The latest and greenest generation of ionic liquids (ILs) are deep eutectic solvents (DESs) and natural deep eutectic solvents (NADESs); these have shown great promise for various applications and have attracted considerable attention from researchers who seek versatile solvents with pretreatment, extraction, and catalysis capabilities in biomass- and biowaste-to-bioenergy conversion processes. The present work aimed to review the use of DESs and NADESs in the valorization of biomass and biowaste as pretreatment or extraction solvents or catalysis agents.

“…It is mature and well established technique for commercial application [4][5][6]. Aqueous alkanolamines are commonly utilized chemical solvents in absorption process [7]. Alkanolamines are further classified into primary, secondary, tertiary, and sterically hindered amines such as monoethanolamine (MEA), diethanolamine (DEA), N-methyldiethanolamine (MDEA), and 2amino-2-methyl-1-propanol (AMP) respectively [8][9][10].…”

High-pressure absorption study of CO2 in aqueous N-methyldiethanolamine (MDEA) and MDEA-piperazine (PZ)-1-butyl-3-methylimidazolium trifluoromethanesulfonate [bmim][OTf] hybrid solvents. Abstract:In present study, high pressure CO2 absorption performance of aqueous N-methyldiethanolamine (MDEA) and its hybrid solvents with anhydrous piperazine (PZ) and ionic liquid (IL) 1-butyl-3-methylimidazolium trifluoromethanesulfonate [bmim][OTf] were investigated. The absorption performance of hybrid solvents were carried out to investigate CO2 loading capacity (mol of CO2/mol of solvent), and apparent absorption rate (CO2 capture efficiency, overall rate constant). The CO2 loading capacity of aqueous MDEA and its hybrid solvents were experimentally investigated for a wide range of compositions between pressure ranges of 2 to 50 bar and at three different temperatures (303.15, 313.15, and 333.15 K). Furthermore, apparent absorption rate performance of hybrid solvents were determined at 303.15 K temperature and 2 bar pressure. The effect of temperature, CO2 partial pressure, and ionic liquid (IL) concentrations on CO2 loading of aqueous IL-amines hybrid solvent were also investigated. The results indicated that CO2 loading of hybrid solvents were increased with ACCEPTED MANUSCRIPTA C C E P T E D M A N U S C R I P T 2 increase in CO2 partial pressure and IL concentration (up to 10 wt. %), further increased concentration of IL suppressed CO2 loading capacity. The CO2 loading capacity of hybrid solvents were also reduced with rise in system's temperature. The addition of IL and anhydrous PZ significantly enhanced CO2 capture efficiency (nCO2) and overall absorption rate constant (k) of aqueous MDEA solvent.
