英文摘要the molar heat capacities of the azeotrope in the binary system of water and ethanol were measured by an adiabatic calorimeter in the temperature range from 78 k to 320 k. the functions of the heat capacity with respect to the thermodynamic temperature were established. the glass transition occurred at 98. 496 k. the phase transitions took place in the temperature ranges from 123.08 k to 156.96 k and 269.03 k to 273.20 k corresponding to the solid-solid phase transition of ethanol, solid-liquid phase transition of ethanol, and solid-liquid phase transition of water, respectively. the thermodynamic functions and the excess thermodynamic functions of the azeotrope relative to 298.15 k were derived based on the relationships of the thermodynamic functions and the function of the measured heat capacity with respect to the temperature.
