VOLUMETRIC, VISCOMETRIC AND ULTRASONIC BEHAVIOR OF N-HEPTANE WITH ISOMERIC ALCOHOLS AT 298.15K

The ultrasonic velocity, density and viscosity have been measured in t he binary liquid mixtures of n-heptane with n-propanol, iso-propanol, n-butanol and isobutanol over the entire range of mole fractions at a constant temperature of 298.15 K. These data have been used for comput ing the molar volume, internal pressure and enthalpy of the said mixtu res. The positive contribution on V-E, H-E and negative contribution o n pi(i)(E), n(E), indicate the absence of complex formation in the mix tures.
