%X In this study, ionic liquid-amine (BMIM AC+MEA) hybrid solvent was prepared for CO2 capture and its properties were investigated. The hybrid solvent was prepared at different ratios of ionic liquid-amine concentration. The properties such as density, viscosity and refractive index of aqueous ionic liquid-amine (BMIMAC+MEA) hybrid solvent were investigated at different ionic liquid to amine mass ratios of 0.33, 0.6, 1, 1.33 and 1.67 and ionic liquid-amine hybrid mass fraction(w1+w2) % in the aqueous solution of (0.1+0.3), (0.2+0.3), (0.3+0.3), (0.4+0.3), (0.5+0.3) wt.% respectively. The temperature used for each sample investigation was varied from 298.15-313.15 K at the intervals of 5 k. From the investigation conducted, it was demonstrated that increasing the concentration of ionic liquids in the aqueous ionic liquid-amine hybrid solvent increased the density, viscosity as well as refractive index of the hybrid solvent. The temperature has a reverse effect on these properties though the effect of temperature on viscosity at a higher temperature greater than 340 k is less dependent on the concentration of the hybrid solvent. It was also observed that small change in temperature has a negligible effect on the density of hybrid solvent. © 2016 The Authors.
