The effect of cation change (imidazolium, pyridinium, and pyrrolidinium) on the thermophysical properties and sorption capacities was also discussed. The densities and the activation energies of the tested ILs exhibited minor differences. Furthermore, the COSMO-RS model was used to predict the free volumes of ILs aiming to investigate its influence on gas solubilities. The conducted calculations have revealed an antibate correlation between the fractional free volume (FFV) and Henry\u2019s law constant. In particular, the lowest FFV in 1-methylimidazolium [doc] corresponded to the minimal sorption and vice versa. In addition, it was shown that the presence of protic cation results in a significant reduction in CO2 and H2S solubilities. In general, the solubility measurement results of the synthesized ILs have shown their superiority compared to fluorinated ILs based on the physical absorption mechanism.<\/jats:p>","DOI":"10.3390\/membranes13020238","type":"journal-article","created":{"date-parts":[[2023,2,17]],"date-time":"2023-02-17T01:32:56Z","timestamp":1676597576000},"page":"238","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Cation Effect on the Free Volume and the Solubility of H2S and CO2 in Ionic Liquids Based on Bis(2-Ethylhexyl) Sulfosuccinate Anion"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2580-821X","authenticated-orcid":false,"given":"Tatyana S.","family":"Sazanova","sequence":"first","affiliation":[{"name":"Laboratory of SMART Polymeric Materials and Technologies, Mendeleev University of Chemical Technology, 9 Miusskaya Sq., 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alsu I.","family":"Akhmetshina","sequence":"additional","affiliation":[{"name":"Department of Technologies for the Processing of Polymers and Composite Materials, Kazan National Research Technological University, 68 Karl Marx Str., 420015 Kazan, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4904-7622","authenticated-orcid":false,"given":"Anton N.","family":"Petukhov","sequence":"additional","affiliation":[{"name":"Laboratory of SMART Polymeric Materials and Technologies, Mendeleev University of Chemical Technology, 9 Miusskaya Sq., 125047 Moscow, Russia"},{"name":"Chemical Engineering Laboratory, Research Institute for Chemistry, N.I.
