ABSTRACT
Abstract The densities of (octane + benzene) were measured at elevated pressures (0.1 to 40) MPa at four temperatures over the range (298.15 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
