Phase equilibrium and critical lines in n-pentane + water and n-hexane + water systems

Results are given of experimental investigation of the thermal properties of n-pentane + water and n-hexane + water binary systems in the temperature range from 300 to 680 K at pressures up to 60 MPa in a wide density range. Measurements are performed for several values of concentration. The investigations cover the region of liquid-liquid, liquid-vapor, and gas-gas phase equilibria and extend to the homogeneous region. Lines of phase equilibrium and critical lines of these systems are obtained.
