Phase equilibrium and $PVT$-properties of $0.7223$ $\text{H}_2\text{O} + 0.1242$ $n$–$\text{C}_6\text{H}_{14} + 0.1535$ $n$–$\text{C}_3\text{H}_7\text{OH}$ ternary system

The results are given of experimental investigation of the $PVT$-properties and liquid-liquid and liquid-vapor phase equilibria of $0.7223$ $\text{H}_2\text{O} + 0.1242$ $n$–$\text{C}_6\text{H}_{14} + 0.1535$ $n$–$\text{C}_3\text{H}_7\text{OH}$ ternary system along six different isochores. The measurements are performed by the constant-volume piezometer technique in the range of temperature from $309.26$ to $678.82$ K, density from $81.0$ to $485.0$ kg/m$^3$, and pressure up to $60$ MPa. The behavior of the system in the vicinity of the liquid-liquid and liquid-vapor critical points is treated using the scaling equations. The $PVT$-properties are described by the Peng–Robinson equation.
