N2 - The densities of water-methanol and water-ethanol mixtures were measured with the laser-doppler type vibrating tube densimeter at 673.15 K in the pressure range of 25-40 MPa. The excess molar volumes VEMm for all mixtures studied were evaluated from the experimental values, and the dependences of alcohol composition for VEMm were fitted with Redlich-Kister equation. For all mixtures studied, VEM m are positive deviations from the ideal mixtures in the whole composition range at 673.15 K. The composition dependences of V EMm show maxima around 30-40 mol% of alcohol in water and the pressure dependences of VEMm around 30 MPa at 673.15 K.
