“…These analysis of the NMR spectra, together with the Walden plots and the study of the ionicity and of the evolution of the diffusion coefficients as a function of the fluidity, are compatible with coordination of the lithium ion by the functionalized IL as already observed in the literature [24,36,37].…”

Effect of Nitrile-Functionalization of Imidazolium-Based Ionic Liquids on Their Transport Properties, Both Pure and Mixed with Lithium Salts

et al. 2014

The influence of the presence of a nitrile group in the cation of imidazoliumbased ionic liquids on their transport properties was investigated. As these liquids can be used as electrolytes in lithium ion batteries, their mixtures with lithium salts were also considered. 1-Butyl-3-methylimidazolium bis(trifluoromethylsulphonyl)imide, [C 1 C 4 Im] [NTf 2 ], 1-butylnitril-3-methylimidazolium bis(trifluoromethylsulphonyl)imide, [C 1 C 3 CNIm] [NTf 2 ], and their mixtures with bis(trifluoromethylsulphonyl)imide lithium, Li[NTf 2 ], were studied. Their mass transport properties (viscosity, ionic conductivity, self-diffusion) were experimentally determined. NMR spectroscopy was also used to explore molecular organization and interactions in these systems. The addition of a cyano group increases the viscosity and the ionicity of the liquid. The effect of lithium ion is more pronounced on [C 1 C 3 CNIm][NTf 2 ], with interactions between Li ? and the nitrile group.

“…The thermodynamic properties have been reported in the previous reports [15,16] which included the capability to dissolve CO 2 in room temperature condition. For the current study purpose, all the CO 2 solubility data were fitted to obtain a single CO 2 solubility point at 0.06 MPa in order to allow it to be comparable.…”

The absorption of carbon dioxide (CO 2 ) in phosphorous-based ionic liquids was studied theoretically by the molecular modeling ab initio density functional theory (dispersion-corrected B3LYP) and second-order Møller-Plesset perturbation methods. Several types of phosphate-and phosphite-based anions were employed and the calculation results were compared with recent published papers. The interaction energy between CO 2 and anion, following the result of Bhargava and Balasubramanian, was calculated in order to have a better understanding on the effect of different functional groups on the interaction between CO 2 and anion. The computational results indicated that the molar volume of the anion molecules played an important role on the absorption mechanism of CO 2 due to the CO 2 -philicity of carbonyl and alkyl groups.

“…The length of alkyl-side chain of imidazolium based cations also affects the CO 2 solubility (Table 1). Fluoro-substituted side chains increase CO 2 uptake greatly rather than fluorine-nonsubstituted side chains but substantially this causes [29] increase in the viscosity [30][31][32]. Anion appears to be of more powerful effect on the gas solubility than cations.…”

Carbon dioxide (CO 2 ) capture is a global concern because of its effect on climate change especially as regards to global warming. Among greenhouse gases, CO 2 is the most abundant with high concentration released from post combustion processes into the atmosphere. For instance, the volume of CO 2 emission from thermal power plants, petroleum refineries, petrochemical plants, hydrogen and cement factories has become one of the top important global concerns nowadays. In order to capture post-combustion CO 2 and securely store it way or to produce useful products from it, it requires separation of CO 2 from flue gas stream. Industrially, it is generally accepted that the most appropriate method that can be applied commercially to capture CO 2 involves absorbing it with a reversible reaction from gas streams into aqueous amine especially monoethanolamine. Although, CO 2 -aqueous amine process is accepted as a mature technology but its absorption/desorption systems are the subject of several studies as the process is energy-intensive among other issues. In view of the shortfalls of CO 2 -aqueous amine systems and the greater societal concern to control the amount of CO 2 released to the environment from industrial sources to abate its effects, research for alternative viable solvent systems becomes of high interest to researchers as well as industrialists. Hence, this chapter is mainly to focus on highlighting and discussing relevant advanced solvent systems for CO 2 capture. Among the novel solvents or technology worthy of discussion here include use of organic solvents consisting of an amidine or a guanidine and a linear alcohol, such as 1-hexanol, instead of aqueous amines. In this case, CO 2 loaded solvent could be regenerated at 90-100°C which is much lower than the boiling point of the solvent and as a result, sufficient drop in energy requirements could be
