| Abstract: | The low-temperature heat capacity of cyclohexane was precisely determined with an automated adiabatic calorimeter over the temperature range from 80 to 340 K. The relationship of molar heat capacity of cyclohexane with respect to thermodynamic temperature has been established. The changes of ther-modynamic functions of cyclohexane in liquid phase were calculated based on the relationships of thermodynamic functions. The chemical purity of the cyclohexane was determined. |
