The thermal properties of water-ethanol system in the near-critical and supercritical states

Experimental p , ρ, T , x -data are given for water-ethanol mixtures at temperatures up to 673.15 K, including the saturation curve and the critical and supercritical regions, and at pressures up to 50 MPa for ethanol concentrations of 0.2, 0.5, and 0.8 mole fraction. The data of p , ρ, T , x -measurements are used to determine the critical parameters of mixtures. The thermal decomposition of ethanol molecules is observed at a temperature above 623.15 K.
