description: The present study aims to investigate the temperature dependence of the physicochemical properties of four cations (namely 2-chloro-1,3-dimethylimidazolium diMeim, 3-benzyl-5-(2-hydroxyethyl)-4-thiazolium bnthia, (chloromethylene)dimethyl iminium diMeimi and morpholinium mrph) paired with common 2-acrylamido-2methyl-1-propanesulfonate AMPS anion. The density and viscosity of the resulting ionic liquids (ILs) were measured within temperature range of (293.15�363.15) K while refractive indexes were determined within temperature range of (288.15�333.15) K. Among the investigated novel ILs, bnthiaAMPS showed the highest viscosity and density over the entire temperature range and an enhanced CO2 dissolution of 0.65 mol fraction was observed at 1 MPa and 298.15 K. Furthermore, the Henry's constant of bnthiaAMPS was found to be 1.199 MPa which was 23.7, 32.6, and 56.0% less than diMeimAMPS, diMeimiAMPS and mrphAMPS, respectively. The present study provides a detailed insight to understand structure-activity relation between physicochemical properties and CO2 solubility of studied ILs. © 2019 Elsevier B.V.
