In this work, the interplay between asphaltene and ILs has been studied systematically to understand the effect of structural variation of ILs on asphaltene solubility. The activity coefficient of the total of 1517 ILs with different combinations of cation and anion of ILs for representative asphaltene molecule (asphaltene) was estimated via COSMO-RS (Conductor-like Screening Model for Real Solvents). COSMORS predictions were validated using experimental data on asphaltene solubility. Among the studied ILs, asphaltene showed high solubility in imidazolium-based ILs with hydrophobic anions. The present approach paved a way forward to rationally understand the impact of structural variation of ILs on their interaction with asphaltene molecule and to design new ILs for the dispersion and stabilization of asphaltene. © 2019 The Korean Society of Industrial and Engineering Chemistry date: 2019 publisher: Korean Society of Industrial Engineering Chemistry official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85069734016&doi=10.1016%2fj.jiec.2019.06.034&partnerID=40&md5=1e05e4c140295a7b9dfa49122b120164 id_number: 10.1016/j.jiec.2019.06.034 full_text_status: none publication: Journal of Industrial and Engineering Chemistry volume: 79 pagerange: 194-203 refereed: TRUE issn: 1226086X citation: Rashid, Z. and Wilfred, C.D. and Iyyaswami, R. and Appusamy, A. and Thanabalan, M.
