Viscosity, Density and Excess Volume of Acetone + Carbon Dioxide Mixtures at High Pressures

摘要: The densities and viscosities of acetone, carbon dioxide, acetone + dioxide mixtures containing 10, 25, 50, 75 wt % were determined at nominal temperatures 325, 348, 373, 398 K pressures up to 35 MPa using a falling-cylinder type high-pressure viscometer. found show crossovers around 18 for with CO2 content less than 50 23 greater 325 K, which shifts higher temperature. Acetone displayed the mixtures. At negative excess volumes all compositions lower 28 MPa. become increasing pressure are positive above high content; 55 MPa, they compositions.
