Densities and viscosities of 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) (1) + N-methyl-2-pyrrolidone (NMP) (2) with w 1 = 0.0000, 0.5000, 0.6999, 0.8981, and 1.0000 at T = (298.15 to 318.15) K were measured and fitted to standard equations. The results show that densities and viscosities of the hybrid solvents decrease with the increase of temperature and mass fraction of NMP. A high-pressure variable-volume view cell technique was used to determine the solubility of CO2 in pure solvents and mixtures under elevated pressures up to 6 MPa at temperatures from (298.15 to 318.15) K. The results indicate that the solubility of CO2 in the pure solvents and mixtures increases with the increase of pressure and with the decrease of temperature. The solubility of CO2 in the mixtures increases with the increase of the mass fraction of NMP, but it is very close to that in pure [bmim][BF4] as the mass fraction of NMP is around 0.1019.

Alkanolamine solutions are used in the industry worldwide to remove carbon dioxide and hydrogen sulfide from natural gas, but such technologies have disadvantages. This study aimed to investigate the new hybrid amine solvents for carbon dioxide capture and their potential to reduce the disadvantages of amine technology. The solubility of carbon dioxide in hybrid solvents with different mixtures of monoethanolamine, water, n-methyl-2-pyrrolidone, 1-butyl-3-methylimidazolium trifluoromethanesulfonate, and 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide was measured at temperatures of 298.15 and 313.15 K by a static synthetic method. The viscosity, density, speed of sound, and evaporation rates for the hybrid solvents were also measured. Experimental observations indicate that the solubility of carbon dioxide in a hybrid solvent of n-methyl-2-pyrrolidone + monoethanolamine was greater than that of the aqueous amine solvent, except at low pressures depending on the concentration of amine. The addition of an ionic liquid to the amine solution reduced the volatility of the solvent and decelerated the evaporation rate of amine, while the loss of ionic liquid was almost zero. However, the addition of an ionic liquid to n-methyl-2-pyrrolidone-containing monoethanolamine solvent or the aqueous monoethanolamine solvent decreased the solubility of carbon dioxide and increased the viscosity of the solution.

“…Five widely employed extractive distillation solvents for separating the mixtures of cyclohexane (A) and benzene (B) are listed in Table 4 based on extensive literature research. 61,[63][64][65][66] However, all these solvents have some drawbacks, such as toxicity or ecological hazard. The toxicity and ecological information of these solvents (with experimentally measured or predicted properties) is available in the Syntelly database.…”
