In this study, the phase behavior of binary systems of squalane (C30H62, 2,6,10,15,19,23-hexamethyltetracosane) with ethane, and propane, is investigated. For both systems, vapor-liquid equilibrium data were measured using the synthetic method in the temperature range (263 to 473) K and pressure range (0.2 to 16) MPa. Also a liquid-liquid-vapor curve was determined for the ethane + squalane system. The experiments were carried out for various mixtures covering almost the whole composition range. Additionally, the experimental data have been modeled using the Soave-Redlich-Kwong equation of state using two adjustable parameters in the classical mixing rules.
