Abstract
En 中文
This update to the previous perspective summarizes recent work in the area of gas solubilities in ionic liquids over the last four years (2017-2020). As research into applications of ionic liquids, especially for gas separations, continues to gain momentum, the importance of understanding the gas + ionic liquid global phase behavior is paramount. The majority of experimental gas solubility studies tend to focus on classic methods like the gravimetric microbalance method and the stoichiometric pressure drop method. There continues to be a significant amount of work on modeling ionic liquids using correlative equation of state to simply model the thermodynamic behavior or purely predictive modeling such as molecular dynamics. The combination of these techniques can be a powerful tool for further understanding of the global phase behavior of gas + ionic liquid systems as well as the screening and/or task-specific design of ionic liquids for specific purposes.
