“…In these experiments they found that, with the same cation CO 2 solubility in TFA-based BAILs are higher than that in FBA-based ones. 594 Mumford et al recently evaluated the protic ionic liquid ethylenediamine N,N-dimethylaminoethylammonium formate for the removal of CO 2 from N 2 mixed gas streams. 596 This evaluation was conducted by comparison with the industrial standard 30 wt % monoethanolamine (MEA).…”

Ionic liquid with acidic properties is an important branch in the wide ionic liquid field and the aim of this article is to cover all aspects of these acidic ionic liquids, especially focusing on the developments in the last four years. The structural diversity and synthesis of acidic ionic liquids are discussed in the introduction sections of this review. In addition, an unambiguous classification system for various types of acidic ionic liquids is presented in the introduction. The physical properties including acidity, thermo-physical properties, ionic conductivity, spectroscopy, and computational studies on acidic ionic liquids are covered in the next sections. The final section provides a comprehensive review on applications of acidic ionic liquids in a wide array of fields including catalysis, CO2 fixation, ionogel, electrolyte, fuel-cell, membrane, biomass processing, biodiesel synthesis, desulfurization of gasoline/diesel, metal processing, and metal electrodeposition.

1-allyloxy-3-(4-nonylphenoxy)-2-propanol polyoxyethylene ethers (ANAPEs), a new type of absorbent, are polymeric surfactants with different adduct numbers. In this work, ANAPEs, including SN-10 with adduct number of 10 and SN-15 with adduct number of 15, were prepared for CO 2 absorption using the isochoric saturation method. Densities of the ANAPEs at atmospheric pressure were measured by a 5.567 ± 0.004 cm 3 pycnometer, which decreased with increased temperature. Solubility data of CO 2 in ANAPEs were measured within the pressure range of 0 - 600.0 kPa and temperature range of 303.15 - 323.15 K at 10 K intervals and could be calculated on the basis of experimental data of p, x CO2 and b CO2 . The solubility of CO 2 in absorbents increased linearly with increasing pressure and decreased with increasing temperature at all the pressures. The solubility of CO 2 in SN-15 is the highest at all temperatures, but almost the same with SN-10 at 303.15 K over pressures (p < 350kPa), which indicates physical dissolution process. Henry's constants were determined from solubility data. With increasing temperature, Henry's constants increased. Thermodynamics of CO 2 absorption were calculated including enthalpy, entropy, and Gibbs energy. The absolute value of Δ sol H based on H x of SN-15 is largest at 303.15 K and indicates stronger SN-15/CO 2 interactions, consistent with solubility of CO 2 based on H x . The negative enthalpy demonstrated exothermic process, which means the dissolution of CO 2 in ANAPEs is favourable enthalpically. The Δ sol G shows positive value.

“…1 and the Experimental procedure was described in detail in our previous works. [39][40][41][42] The apparatus was mainly made up of a SO 2 cylinder, constant temperature water baths with a precision of AE0.05 K, a SO 2 Gas Reservoir (4, GR), Equilibrium Chamber (5, EC) with magnetic stirrer, pressure transmitter and digital indicator. The volumes of EC and GR were measured in our previous reported method 39 with the results of 141.61 cm 3 and 370.99 cm 3 , respectively.…”
