ABSTRACT

Excess enthalpies, densities, and speeds of sound at the temperatures (283.15, 298.15, 313.15) K are reported for the binary mixtures ss-pinene + ethanol and ss-pinene + 1-propanol. Excess molar volumes have been calculated from the densities. The deviations in the speeds of sound have also been estimated. All the properties have been fitted to Pade approximants. Excess molar enthalpies and excess molar volumes are positive for both mixtures while speed of sound deviations show negative values. The values of these properties are discussed in terms of the molecular interactions. The enthalpic and volumetric behaviors of the mixtures are compared with those of the mixtures of ethanol or 1-propanol with cyclohexane or methylcyclohexane which are two simple hydrocarbons whose basic ring is similar to that of b-pinene.
