AbstractThe molar heat capacities of the pure samples of acetone and methanol, and the azeotropic mixture composed of acetone and methanol were measured with an adiabatic calorimeter in the temperature range 78-320 K. The solid-solid and solid-liquid phase transitions of the pure samples and the mixture were determined based on the curve of the heat capacity with respect to temperature. The phase transitions took place at 126.16 +/- 0.68 and 178.96 +/- 1.47 K for the sample of acetone, 157.79 +/- 0.95 and 175.93 +/- 0.95 K for methanol, which were corresponding to the solid-solid and the solid-liquid phase transitions of the acetone and the methanol, respectively. And the phase transitions occurred at 126.58 +/- 0.24, 157.16 +/- 0.42, 175.50 +/- 0.46 and 179.74 +/- 0.89 K corresponding to the solid-solid and the solid-liquid phase transitions of the acetone and the methanol in the mixture, respectively. The thermodynamic functions and the excess thermodynamic functions of the mixture relative to standard temperature 298.15 K were derived based on the relationships of the thermodynamic functions and the function of the measured heat capacity with respect to temperature.
