ABSTRACT

Densities and viscosities for p-xylene with cyclohexane, heptane, octane, and N-methyl-2-pyrrolidone were determined from (298.15 to 353.15) K and at atmospheric pressure. The measurements were carried out over the whole range of composition, using a vibrating-tube density meter and a Ubbelohde viscometer. Density and viscosity measurements were used to compute the excess molar volumes, VE, and viscosity deviations. The excess molar volumes, VE, and viscosity deviations, have been fit to the Redlich-Kister equation, and the coefficients and estimates of the standard error values are given.
