The thermal properties of a water-methanol system with a composition of $0.5$ mass fraction at temperatures from $373.15$ to $673.15$ K and pressures up to $60$ MPa

Results are given of measurements of the pressure, density, and temperature of a mixture of water with methyl alcohol (methanol) with a composition of $0.5$ mass fraction in the subcritical, critical, and supercritical regions of state parameters. The measurements are performed by the piezometer method at constant volume. The isotherms and isochors of $p$, $\rho$-dependences are used to determine the regions of the two-phase liquid-vapor state and single-phase gas state and to estimate the values of the critical parameters of the mixture.
