• Abstract: Ionic liquids are applicable in the recovery of valuable products, remotion of polluting agents, and used in many CO2-capture techniques. In this work, high-pressure vapor-liquid equilibria of twenty-one binary mixtures of light hydrocarbons + IL has been modelled with Peng-Robinson/Stryjek-Vera equation of state applying Wong-Sandler mixing rules and van Laar model for the gamma-phi approach and Perturbed Chain-Statistical Associating Fluid Theory equation of state for the phi-phi approach. Critical properties were determined using a group contribution method. Adjustable characteristic pure component parame- ters were obtained using predicted vapor pressures and saturated liquids densities values. Experimental data, obtained from literature, were subjected to thermodynamic consistency area test. For the thermody- namic modelling, adjustable parameters were fitted between predicted and experimental bubble pressure. Van Laar and interaction parameters were regarded as temperature-dependent. Results obtained for both models, in terms of the main deviations between experimental and calculated pressures, were reasonably satisfactory. © 2021 Elsevier B.V. All rights reserved. 1. Introduction The interest in ionic liquids (IL) as solvents for chemical pro- cesses is because these compounds are thermally stable, have high polarity, remain unchanged when mixed with various organic com- pounds, have a very small vapor pressure as catalysts, are liquids in a wide temperature range, and are capable of being miscible and immiscible with organic or inorganic substances [1,2]. This set of properties allows for the design of attractive reaction systems that can solve the major disadvantages of some synthesis methods cur- rently employed or open new processes for making products [3]. An additional key factor for the functional characteristics of these solvents is their environmental compatibility [4]. They curr
