Room-temperature ionic liquids (RTILs or ILs) and carbon dioxide have been categorized as green solvents and investigated for a wide range of industrial applications. Binary systems involving ionic liquids (ILs) and carbon dioxide (CO2) form the basis of many applications as replacement solvents. In this work, Excess molar enthalpies for binary systems of 1-butyl-3-methylimidazolium chloride [BMIM][Cl], ionic liquid + alcohols at atmospheric pressure were measured with two HPLC pumps and isothermal microcalorimeter (Model : CSC-6238) and correlated by using the UNIQUAC equation. and excess molar enthalpies for binary systems of carbon dioxide + (ionic liquid + alcohols) at high pressures were determined by using a high pressure flow-mixing isothermal microcalorimeter . The experimental data were correlated by using the Peng-Robinson equation and GC-NLF equation. |
