Phase equilibria and saturated densities were measured at 308.15 K and 313.15 K with a static-circulation apparatus for ethane + 2-propanol at high pressures. An experimental apparatus equipped with three Anton Paar DMA 512S vibrating tube density meters had been previously developed for measuring vapor-liquid-liquid phase separation properties at high pressures. Coexisting phase compositions and saturated densities of each phase could be measured with the apparatus with a maximum temperature and pressure of 400 K and 20 MPa, respectively. For the present system, Kuenen et al. (Philos. Mag. 1899, 48, 180203) had previously reported only the upper critical end point and the approximate lower critical end point. In the present study, the vapor-liquid equilibrium composition and saturated density of each phase were determined by gas chromatography and density measurements, respectively. Vapor-liquid-liquid equilibria was not observed in the present experiments. The experimental data obtained were correlated with equations of state.
