Density measurements at given temperatures and pressures in the compressed liquid phase for a constant-composition mixture of {xCH3CH2OH + (1-x)H2O} with x = (0.6533±0.0005) were carried out with a metal-bellows variable volumometer. The results cover the high-density region from 1105 kg·m-3 to 1496 kg·m-3 along seven isotherms between 310 K and 420 K at pressures from 0.1 MPa to 200 MPa. The experimental uncertainties of temperature T, pressure p, and density ρ were estimated to be ≯|3 mK|, |0.0010·p|, and |0.0010·ρ|, respectively. On the basis of the present results, the excess molar volume, the isothermal compressibility, and the isobaric expansivity were calculated.
