    (p, Vm, T) Measurements of (Octane + Benzene) at Temperatures from 298.15 K to 328.15 K and at Pressures up to 40 MPa

  • Original language description

    The densities of the octane + benzene system were measured at elevated pressures (0.1 to 40) MPa at four temperatures over the range 298.15 K to 328.15 K with a high-pressure apparatus. The high-pressure density data were fitted to the Tait equation andthe isothermal compressibilities were calculated with a novel computation procedure with the aid of this equation. The low- and high-pressure values of excess molar volume calculated from the density data show that the deviations from ideal behaviour inthe system are practically independent of temperature and decreases slightly as the pressure is raised. The excess molar volume data were fitted to the fourth-order Redlich?Kister equation, with the maximum likelihood principle being applied for the determination of the adjustable parameters.

    Měření stavového chování systému oktan + benzen při teplotách 298.15 K až 328.15 K a při tlacích až 40 MPa

  • Czech description

    Změřili jsme hustoty v systému oktan + benzen za zvýšených tlaků (0.1 až 40) MPa při čtyřech teplotách v rozmezí 298.15 až 328.15 K pomocí vysokotlaké aparatury. Tato data byla vyrovnána Taitovou rovnicí a z ní byly vypočteny isotermní kompresibility pomocí nově navrženého postupu. Dále byly z těchto hustot vypočteny dodatkové molární objemy, které jsou prakticky nezávislé na teplotě a poněkud klesají se zvyšujícím se tlakem. Dodatkové objemy byly vyrovnány Redlichovou-Kisterovou rovnicí.
