    (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 (octane plus benzene) 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 and the 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 in the system are practically independent of temperature and decreases slightly as the 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 oktan + benzen při teplotách (298,15 K až 328,15) K a při tlacích do 40 MPa

  • Czech description

    Hustoty systému oktan plus benzene byly měřeny při vysokých tlacích (0,1 až 40) MPa při čtyřech teplotách v rozmezí 298,15 K až 328,15 K pomocí vysokotlaké aparatury. Hustoty byly korelovány Taitovou rovnicí a isothermní kompresibility byly vypočteny novou výpočetní metodou pomocí této rovnice. Dodatkové objemy vypočtené ze změřených hustot ukazují, že odchylky od ideality jsou prakticky nezávislé na teplotě a mírně klesají s rostoucím tlakem. Dodatkové objemy bylt korelovány Redlichovou?Kisterovou rovnicí.
