Abstract:

Statement of the Problem: In the era of rapidly changing global environment, research attempts have been made to replace fossil fuels for the control of greenhouse gases emissions and environmental pollution. Ionic liquids (ILs) have received widespread attention as an eco-friendly reaction medium for various processes involved in industries. Due to their unique properties (negligible vapor pressure, non-flammability, excellent solubility, non-volatility, reusability, high thermal and electrochemical stability), ILs can be considered as safer and more sustainable alternative to volatile organic compounds (VOCs) used in industries. Experimental density, speeds of sound and their derived properties, excess molar volumes, VE E S κ data of ILs and their mixtures with organic solvents may be of great importance in mass and heat transfer processes of working fluids and thus can be utilized for designing and engineering of such processes. Methodology and Theoretical Orientation: The densities, ρijk and speeds of sound, uijk data of ternary {1-butyl-3- methylimidazolium tetrafluoroborate (i) +1-ethyl-3-methylimidazolium tetrafluoroborate (j) + cyclopentanone or cyclohexanone (k) mixtures have been measured at 293.15 K and 298.15 K using a digital densimeter and speed of sound analyser. The observed ρijk and uijk data have been employed to determine (VE )ijk and E S ijk (κ ) respectively. The (VE )ijk and E S ijk (κ ) data have been fitted to Redlich-Kister equation to see whether the observed data is of required accuracy to be utilized in various industrial processes or not ? The topology of the constituent molecules has been utilized (Graph theory) to obtain information about the state of the components in pure state and also regarding the various processes involved in the mixture formation. Conclusion and Significance: The (VE )ijk and E S ijk (κ ) data predicted by Graph theory compare well with their experimental data. Further the measured data are of required accuracy and can be utilized for designing various processes involving fluid in industries. Recent Publications 1.
