摘要：

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, V-E, and viscosity deviations, Deltaeta. The excess molar volumes, V-E, and viscosity deviations, Deltaeta, have been fit to the Redlich-Kister equation, and the coefficients and estimates of the standard error values are given.
