“…ethanolammonium nitrate and ethylammonium nitrate were reported in 1888 and 1914 by Gabriel and Walden, respectively [20]. The amine-based PILs were also reported by Bicak [21] and by Karadag [22]. Nevertheless, there is only one paper about the PILs based on cyclotriphosphazene with salicylic acid in the literature [23].…”

Abstract:In the present study, the condensation reaction of N3P3Cl6 (1) with sodium 3-(4-fluorobenzylamino)-1-propanoxide gave partly substituted 4-fluorobenzylspirocyclotriphosphazene (2). The Cl replacement reactions of 2 with excess benzylamine, n-hexylamine, n-butylamine and n-propylamine led to the formation of the corresponding 4-fluorobenzylspiro(N/O)tetrabenzylamino (3a), tetrahexylamino (3b), tetrabutylamino (3c) and tetrapropylamino (3d) cyclotriphosphazenes. With the protic ionic liquids (PILs), phosphazenium salts (4a-4d), were obtained from the reactions of the corresponding phosphazene bases (3a-3d) with gentisic acid in dry THF. The structures of all the isolated cyclotriphosphazene derivatives were determined by elemental analyses, FTIR and H} NMR techniques. The crystal structure of 4d was verified by X-ray diffraction analysis. All the compounds were screened for antibacterial and antifungal activities against bacteria and yeast strains. The interactions of the compounds with supercoiled pUC18 plasmid DNA were investigated.

“…The [AEEA] + -based ILs used in this study ([AEEA][X]) were prepared by the neutralization of AEEA with equimolar amounts of the corresponding acids, as reported previously . For example, in the preparation of [AEEA][Tf 2 N] ([Tf 2 N]: bis(trifluoromethanesulfonyl)imide), AEEA and H[Tf 2 N] were mixed in water at a molar ratio of 1.0:1.0 while cooling the solution in an ice bath, and subsequently, the solution was allowed to stir for ≥2 h. After this time, the water was evaporated with a rotary evaporator, and the sample was dried in vacuo to obtain [AEEA][Tf 2 N].…”

Ionic Liquid Mixtures for Direct Air Capture: High CO₂ Permeation Driven by Superior CO₂ Absorption with Lower Absolute Enthalpy

This paper reports a series of liquid materials suitable for use as high-performance separation membranes in direct air capture. Upon mixing two ionic liquids (ILs), namely N-(2-aminoethyl)ethanolamine-based IL ([AEEA][X]) and 1-ethyl-3-methylimidazolium acetate ([emim][AcO]), the resulting mixtures with a specific range of their composition showed higher CO2 absorption rates, larger CO2 solubilities, and lower absolute enthalpies of CO2 absorption compared to those of single ILs. NMR spectroscopy of the IL mixture after exposure to 13CO2 allowed elucidation of the chemisorbed species, wherein [AEEA][X] reacts with CO2 to form CO2–[AEEA]+ complexes stabilized by hydrogen bonding with acetate anions. Supported IL membranes composed of [AEEA][X]/[emim][AcO] mixtures were then fabricated, and the membrane with a suitable mixing ratio showed a CO2 permeability of 25,983 Barrer and a CO2/N2 selectivity of 10,059 at 313.2 K and an applied CO2 partial pressure of 40 Pa without water vapor. These values are higher than those reported for known facilitated transport membranes.

“…Ionic liquids (ILs) are compounds that consist wholly of ions and remain liquid below 100°C. 1 Generally, ILs are composed of bulky organic cations paired with organic or inorganic anions bound together by electrostatic interactions and they have unique physical properties such as negligible vapor pressure, high thermal stability, nonflammability, a wide electrochemical window, and a wide fluid range. 2 ILs can be classified into two broad categories: protic ILs (PILs) and aprotic ILs (APILs).…”

Protic ionic liquids (PILs) were synthesized through a stoichiometric neutralization reaction between 2,2 ′-(ethylenedioxy)-bis(ethylamine) { Edbea} and various acids (formic, acetic, boric, decanoic, and gentisic acid). The PILs were characterized by elemental analyses, FTIR, 1 H and 13 C NMR spectroscopy, and thermogravimetric analysis. All the PILs except PIL3 were liquid at room temperature. The viscosity of the PILs (PIL1, 2, 4, 5) was measured using a cone-and-plate viscometer at ambient temperature. Quantum chemical calculations were used to explain the cation/anion ratio in the PILs. Reaction energies in the gas phase calculated at M062X/6-311 + G(d,p) level were used to determine the cation/anion ratio. A sliding wear test was conducted at room temperature using an AA7075 disc specimen against a stationary 100Cr6 steel ball. The wear protection of PILs and 15W40 engine oil was determined by considering the volume loss of AA7075.
