    Abstract

    In this work, experimental data for vapor-liquid equilibria at 84.49 kPa, densities, and viscosities at 318.15 K are reported for the propanenitrile-decane mixture. To validate the methodology and the equipment selected to perform, the experimental study data for the ethanol-water mixture were measured and it was found that values are consistent with other data reported in the literature. After validation, experimental data for the propanenitrile + decane mixture were measured including liquid-liquid and vapor-liquid equilibria, densities, and viscosities. Finally, phase equilibria and densities were modeled using a modified Peng-Robinson equation of state. Also, the viscosity model proposed by Derevich was used to describe viscosities of pure substances and the Eyring-Wilson-Porter mixing rule was used to predict the viscosity of liquid mixtures. According to the obtained results, the models selected describe the measured thermodynamic and transport properties with low deviations.
