    (P, Vm, T) Measurements of (Cyclohexane + Nonane) at Temperatures from 298.15 K to 328.15 K and at Pressures up to 40 MPa.

  • Original language description

    The densities and speeds of sound of (cyclohexane + nonane) were measured at four temperatures within 298.15 K ? 328.15 K, and the respective values of excess volumes and adiabatic compressibility were calculated. Thereafter the densities for the last system were measured at elevated pressures (0.1 ? 40 MPa) at four temperatures in the range 298.15 K ? 328.15 K with a high-pressure apparatus. The high-pressure density data were fitted to the Tait equation and the isothermal compressibilities were calculated with a novel procedure with the aid of this equation. The low- and high-pressure excess volumes calculated from the density data show that the deviations from ideal behaviour in the system decrease slightly as the temperature and pressure is raised.The data were fitted to the fourth-order Redlich-Kister equation, with the maximum likelihood principle being applied for the determination of the adjustable parameters.

    (P, Vm, T)měření systému cyklohexan + nonan při teplotách od 298.15 K do 328 K a při tlacích do 40 MPa.

  • Czech description

    Hustoty a rychlost zvuku systému cyklohexan + nonan byly změřeny při čtyřech teplotách v rozmezí 298.15 - 328.15 K a hodnoty dodatkových objemů a adiabatické stlačitelnosti byly vypočteny. Poté byly měřeny hustoty daného systému při vysokých tlacích (0.1- 40 MPa) při uvedených čtyřech teplotách pomocí vysokotlaké aparatury. Vysokotlaké hustoty byly fitovány Taitovou rovnicí a izotermní stlačitelnostri byly vypočteny novou vypočtovou metodou. Vypočtené nízkotlaké i vysokotlaké dodatkové objemy ukazují,že odchylky od ideálního mchování v tomto systému klasají při zvyšování teploty i tlaku.
