Densities rho and speeds of sound u for binary mixtures cyclohexylamine + cyclohexane and + benzene have been measured over the entire range of composition at temperatures from 293.15 to 323.15 K using an Anton-Paar DSA 5000. The molar isentropic compressibilities K-S,K-m, Rao's molar sound functions R, thermal expansion coefficients alpha(P), excess molar volumes V-m(E), and excess molar isentropic compressibilities K-S,m(E) have been calculated from these data. V-m(E) and K-S,m(E) for both the mixtures are positive at all temperatures and over entire range of compositions. The values of V-m(E) for cyclohexylamine + cyclohexane increase with rise in temperature while decrease for cyclohexylamine + benzene. The values of alpha(E)(P) are positive for cyclo-hexylamine + cyclohexane and negative for cyclohexylamine + benzene. The results of u, V-m(E), (partial derivative V-m(E)/partial derivative T)(P), and (partial derivative V-m(E)/partial derivative P)(T) are compared with the theoretical predictions of the Prigogine-Flory-Patterson theory.
