Equation of State for C60 Fullerene Aqueous Solutions

In the present work PVT data of the C60 fullerene aqueous solution (C60FAS) were measured as a function of the concentration of C60 molecules using the variable cell method with metal bellows in the temperature range from 295 to 360K at pressures from 0.1 to 103.2MPa. On the liquid–vapor equilibrium line the density (ρ) of the C60FAS was measured using the pycnometer method. As a result, numerical values for the isothermal modulus of elasticity (KT ), isobaric expansivity (αP ), isothermal deviation of entropy factor (TΔS), enthalpy (ΔH), and iInternal energy (ΔU) have been determined. Finally, an equation of state for the C60FAS was obtained for the first time.
