摘要：
The Р, ρ, and Т-properties of a water + n-hexane system immiscible under normal conditions are measured piezometrically in the water mole fraction range of 0.918–0.977 at 309–685 K and pressures of up to 66 MPa. Two phase transitions are observed on each isochore corresponding to phase transitions of hydrocarbon liquid into gas or the dissolution of n-hexane in water and the transition of aqueous liquid into gas. The boundaries of phase transitions and their critical parameters are determined.
