Theory Of Mixtures

Volumetric heat capacities for binary mixtures of n-octane with n-hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, and 2,3-dimethylbutane were measured at 298.15 K in a Picker flow microcalorimeter. The results were combined with previously published excess molar volumes to obtain excess molar isobaric heat capacities. Interpretation of the results in terms of the Flory theory of mixtures is discussed.

Densities, viscosities and ultrasonic velocities were measured for the two ternary liquid mixtures containing morpholine (1) + 1,4-dioxane (2) + nitrobenzene (3) or + toluene (3) at 308.15 K over the entire range of mole fractions. Thermodynamic parameters, such as excess volume (VE), deviations in adiabatic compressibility (?KS), free length (?LF), isothermal compressibility (??T), free volume (?VF) and viscosity (??) were calculated and applied to the Redlich? Kister polynomial equation to determine the appropriate coefficients. The deviations of the ternary liquid mixtures from their ideal behaviour were determined from the measured and calculated thermodynamic properties. In addition, an insight into the molecular structure and possible interactions for the investigated mixtures was attempted.

Theory Of Mixtures

Excess molar volumes, measured at 298.15 K in a tilting dilution dilatometer, are reported for the five binary systems formed by mixing n-octane with n-hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, and 2,3-dimethylbutane. The Flory theory of mixtures provides a reasonable correlation of the results in combination with excess molar enthalpies measured previously.
