Abstract

The molar heat capacities of the binary mixture compound of water and isomeric butyl alcohol were measured with an adiabatic calorimeter at the
temp. 308.15 K. The ultra sonic absorption coefficients in the frequency of 2 MHz. sound velocity, density were measured in the aqueous solutions at
various concentrations. It was speculated that a double relaxational equation of the Debye type is appropriate to represent the absorption data in
the concentration range from 0.001 to 1.000 mol dm‐3 while a single one is fitted in those less than 1.0 down to 0.79 mol dm‐3 For explaining the
ultrasonic relaxation phenomena, the analysis was carried out with a reaction model associated with solute‐solvent interaction. From the
concentration dependence of the relaxation frequencies, the rate and the thermodynamic parameter were evaluated for the two reaction. The
thermodynamic function relative to a temperature of 308.15 K were derived based on the relationships of the thermodynamic functions and the
function of the measured heat capacity with respect to temperature.
