- Abstract: The ionic liquids (ILs) have arisen as a promising alternative to replace solvents such as the volatile organic compounds due to their advantageous properties [1]. Among others several applications, the ILs have also attracted attention in the carbon dioxide capture. The study of the solubility of CO2 implies in a great variety of substances that should be tested in order to find an environmental friendly IL that can replace the amines, the most used substance [2]. An important characteristic of ILs is the tunability of their properties depending on the ions chosen [3]. Once there is an endlessness number of possible combinations, the study of the phase behavior from a few data of the solubility of CO2 in a given IL becomes a key information to save resources. The prediction of a few data from different systems composed by CO2 and an IL is proposed through the thermodynamic modeling using cubic and non-cubic equations of state. In another approach, called thermodynamic simulation, the use of artificial neural networks (ANN) showed to be an efficient method.
