Abstract
We report P-V-T-x measurements for five binary systems: water+methane, water+n-hexane, water+n-octane, water+benzene, and water+nitrogen at supercritical conditions for several compositions. The experimental data were obtained along isotherms with a phase-equilibrium cell designed for accurate measurements at pressures up to 100 MPa. The uncertainties in temperature, pressure, density, and concentration are ±0.01 K, ±0.2%, ±0.2%, and ±0.002 mole fractions, respectively. The behavior of the second virial coefficient, the excess volume, and the excess Gibbs free energy is also discussed.
