“…3a), the values reported by Cadena et al [14], by Camper et al [7,10] and by our research group in a previous study [4] (using the same type of experimental apparatus but another sample of IL) deviate from the present work less than 5%. Another set of data from Camper et al [8] for the same system show a larger deviation specially at the higher temperature end. Finally, two sets of data, reported by Kim et al [17] and by Morgan et al [9], exhibit a difference of more than 5% from the present data.…”

“…The solubility of carbon dioxide in a variety of ILs has been determined at low pressures [1][2][3][4][5][6][7][8][9][10] and high pressures (up to 73 MPa) [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. In particular, the system (carbon dioxide + [C 1 C 2 Im][NTf 2 ]), also investigated in this work, was studied by several authors [7][8][9][10]14,17].…”

“…In particular, the system (carbon dioxide + [C 1 C 2 Im][NTf 2 ]), also investigated in this work, was studied by several authors [7][8][9][10]14,17]. Camper et al [7,8,10] have determined the solubility of carbon dioxide experimentally in this IL from 303 to 343 K and at low pressures by isochoric pVT measurements. The reported Henry's law constants (4.0 MPa at 303 K and 7.7 MPa at 343 K) increase when increasing temperature corresponding to a decrease of the solubility with temperature.…”

Safety and Corrosion 7 References The common definition of an ionic liquid (IL), or a room temperature ionic liquid (RTIL), is that it is a liquid composed entirely of ions, which is fluid below 100 °C. Ionic liquids are generally much denser (ρ = 1 − 1.6 g/cm 3 ) and more viscous (η = 10 − 500 mPa · s) than conventional solvents. Ionic liquids can be stable up to temperatures of 500 °C. They can easily be synthesized and the variability of the cation and anion may be used to adjust the properties of the ionic liquids. Therefore, the possibility arises to optimize an ionic liquid for a specific application by stepwise tuning the relevant solvent properties. For this reason ionic liquids have been referred to as “designer solvents”. The potential to use ionic liquids as novel solvents or fluids for a diverse range of applications has become increasingly apparent. The intrinsic nonvolatile nature of ILs provides an opportunity to reduce, or even completely eliminate, hazardous and toxic emissions to the atmosphere, thus providing the promise for significant environmental benefits. In synthesis and catalysis, ILs have been used as solvents (or solvents and catalysts), with the greatest current effort on using the ILs as alternatives to volatile organic compounds (VOCs). Electrochemical studies have utilized the fact that ILs are liquids rather than solids to provide liquid electrolytes without needing to add an additional solvent. Ionic liquids are also used in separations, replacing volatile solvents. The number of applications on pilot‐plant and commercial scale is still limited, but growing. Although ionic liquids are also known as “green solvents”, this is not always true. They can be corrosive, flammable, or toxic. Due to their nonvolatile nature, ionic liquids are generally considered as having a low impact on the environment and human health, and thus recognized as solvents for green chemistry. However, the impact of ionic liquids on aquatic ecosystems is important given their mild to high solubility in water. Before ionic liquids will be widely used in industry, the effects of ILs on the aquatic environment must be known.
