Abstract
The temperature dependence of heat capacity of C-70 fullerene was stud ied by calorimetry in the range between 6 and 390 K. Phase transitions were established and their thermodynamic characteristics were determi ned. From the experimental data obtained, the thermodynamic functions H degrees (T) - H degrees (O), S degrees (T), G degrees (T) - H degree s (O) for temperatures between 0 and 390 K were calculated. The result s were used to calculate the standard values of Delta(f)S degrees, Del ta(f)G degrees, and logK(f)degrees for the formation of C-70 from grap hite.
