摘要：

Excess molar enthalpies, densities, and speeds of sound at the temperatures (283.15, 298.15, 313.15) K are reported for the binary mixtures 6,6-dimethyl-2-methylenebicyclo[3.1.1]heptane (beta-pinene) + 1-pentanol and beta-pinene + 2-pentanol. Excess molar volumes, speed of sound deviations, isentropic compressibilities, and excess isentropic compressibilities have been calculated from the densities and speeds of sound. The excess properties and property deviations have been fitted to either Redlich-Kister polynomials or Pade approximants to reproduce the experimental data as accurately as possible. Excess properties 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.
