Abstract

The main objective of the research proposal is the development of thermodynamically founded models to correlate and predict solubility data of gases (such as CO2, NH3, H2S, SO2, N2O, among others) in ionic liquids (ILs) and ionic liquid mixtures, for use in environmental industrial applications. Different types of ILs can dissolve almost any material and, therefore, they have unsuspected applications in the chemical, material, and mining industry. Few years ago, the USA organization known as Vision 2020 recommended the study of properties of ionic liquids and of the phase behavior of mixtures containing ionic liquids (liquid-liquid-equilibrium, liquid-gas-equilibrium, partition coefficients, solubility parameters, miscibility, entrainment, and effects of impurities, among others). Some of these aspects have been studied by several researchers during the last years with emphasis on measuring experimental data. Some methods for correlating and predicting mixture behavior have also been proposed in the literature but still the problem is far from being solved.
