However, due to the unlimited structural variations and possible combinations of cations and anions of the ILs, selection of potential ILs for this separation process has been a difficult task. Activity coefficient at infinite dilution is one of the most important thermodynamic properties for preliminary selection of suitable liquid desiccants for water absorption and designing of the natural gas dehydration process. In this paper, COSMO-RS based quantitative structure�property/activity relationship (QSPR/QSAR) models were developed for prediction of activity coefficient of water at infinite dilution in ILs over various temperatures. COSMO-RS based descriptors were generated for 53 ILs (318 data points) at various temperatures. Multiple linear regressions were applied to develop the models. The accuracies of the models were verified by different statistical tests. The model provides a better understanding of the effect of the structural variations of ILs on their affinity for water. © 2016 Taiwan Institute of Chemical Engineers date: 2016 publisher: Taiwan Institute of Chemical Engineers official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84979528604&doi=10.1016%2fj.jtice.2016.06.027&partnerID=40&md5=00ff5c4e2c2b0b9070b16a6b37e91a4a id_number: 10.1016/j.jtice.2016.06.027 full_text_status: none publication: Journal of the Taiwan Institute of Chemical Engineers volume: 66 pagerange: 222-229 refereed: TRUE issn: 18761070 citation: Gonfa, G. and Bustam, M.A. and Shariff, A.M. and Muhammad, N. and Ullah, S.
