High-pressure phase behavior of CO2+1-butyl-3-methylimidazolium chloride system

Equation of state modelling of systems with ionic liquids: Literature review and application with the Cubic Plus Association (CPA) model

“…Quadratic mixing rules have also been used with the Peng-Robinson EoS to correlate CO 2 [60]. Once again, in all these studies, the critical properties of ionic liquids were estimated using the Joback's group contribution method.…”

Dissolution of Trihexyltetradecylphosphonium Chloride in Supercritical CO2

“…For almost two decades, many groups have studied CO 2 interactions with ILs, which has led to IL applications such as CO 2 capture [26,27], catalyst recycling [23,28] and nanomaterial processing [1]. Much of the work to date, both experimental and theoretical, has focused nearly exclusively on various 1-alkyl-3-methyl imidazolium cations in combination with a variety of anions, where the cation alkyl chains used have been typically from C 2 to C 6 [1,23,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. This body of literature can be summarized by two main goals: (1) the measurement of the phase behavior of CO 2 dissolved in ILs; and (2) the quantitation of CO 2 solubility in a bulk phase IL.…”

Solubility of CO2 in three cellulose‐dissolving ionic liquids

“…Comparison between experimental data from Jang et al 17 (●) and data measured in this work (■), both sets of data corresponding to the binary system [Bmim][Cl] + CO 2 at 353.15 K…”

“…GC‐EOS is used also for the correlation of CO 2 equilibrium of methyl imidazolium chloride‐based ILs, as [Bmim][Cl] and [Amim][Cl]. Lopes et al 13 correlated data from Jang et al 17 for the system CO 2 + [Bmim][Cl] to obtain the interaction parameters between groups ‐mimCl and CO 2 . Nonetheless, the experimental data reported by Jang et al deviates largely with respect the values obtained in this work and reported in Section 3.3.…”

“…Thus, knowledge of the phase behavior of the system CO 2 + ILs at high pressure is of crucial importance to properly develop technologies involving these substances. CO 2 solubility in ILs has been experimentally determined by many authors using diverse techniques which can be classified in four categories: (a) Variable‐volume synthetic methods 15‐18 consist on a visual cell whose pressure can be controlled by changing its volume. A mixture CO 2 + IL of known overall composition is prepared and the phase transitions are visually detected in function of P and T while keeping composition constant, thus, an isopleth is measured for every experiment.…”
