Thermodynamic properties of diosgenin determined by oxygen-bomb calorimetry and DSC

The combustion enthalpy of diosgenin was determined by oxygen-bomb calorimetry. The standard mole combustion enthalpy and the standard mole formation enthalpy have been calculated to be −16098.68 and −528.52 kJ mol −1 , respectively. Fusion enthalpy and melting temperature for diosgenin were also me...

More Information
Summary:The combustion enthalpy of diosgenin was determined by oxygen-bomb calorimetry. The standard mole combustion enthalpy and the standard mole formation enthalpy have been calculated to be −16098.68 and −528.52 kJ mol −1 , respectively. Fusion enthalpy and melting temperature for diosgenin were also measured to be −34.43 kJ mol −1 and 212.33°C, respectively, according to differential scanning calorimetry (DSC) data. These studies can provide useful thermodynamic data for this compound.
