Excess Molar Volumes and Surface Tensions of Xylene with 2-Propanol or 2-Methyl-2-propanol at 298.15 K

Densities for binary mixtures of (2-propanol + o -xylene, + m -xylene, + p -xylene, 2-methyl-2-propanol + o -xylene, + m -xylene, and + p -xylene) have been determined at 298.15 K, and excess molar volumes have been derived. Surface tension of these binary mixtures have been measured at 298.15 K by the pendant drop method, and the values of the surface tension deviation for these mixtures were also calculated.
