In the present investigation, the heat capacity of fullerenol C60(OH)24 was measured by precision adiabatic and differential scanning calorimetry over the temperature range from T = (6 to 670) K. The keto-enol tautomerism was revealed in the temperature range T = (355–575) K and enthalpy of transition was determined. The standard thermodynamic functions: molar heat capacity Cp°, enthalpy [H°(T) − H°(0)], entropy S°(T), and Gibbs energy [G°(T) − H°(0)] of the fullerenol were determined over the temperature range from T = (6 to 350) K from the obtained experimental results. Also, DFT calculations of the heat capacities were performed. The standard thermodynamic properties of the investigated fullerenol were compared to other fullerene derivatives.
